As a credentialed veterinary technician, I have dedicated my career to the idea of “lifelong learning” as outlined in the Veterinary Technician Oath. This commitment extends to both my personal development and assisting others in achieving their goals. A significant part of my career has been focused on caring for my patients, particularly feline patients. Serving as a patient advocate is a great privilege that I hold dear. Being their voice in times of need, providing support, and ensuring their well-being are the most rewarding aspects of my role as a veterinary technician. Early in my career, this meant acquiring as much knowledge and skill as possible to effectively advocate for my patients. As my career has progressed, I have transitioned into sharing knowledge with others so they, too, can become the best veterinary technicians and patient advocates they can be.
This book is designed for clinical veterinary technicians working with feline patients. It caters to those working in multi-species hospitals as well as those exclusively with feline patients, offering comprehensive knowledge about this species. It also targets individuals aspiring to become a feline veterinary technician specialist. The book covers a broad knowledge base of feline diseases, including physical examination findings, clinical signs, and step-by-step procedure lists for common diagnostic techniques.
The book is divided into sections that address patient care needs and special considerations for feline patients, as well as systematic diseases and conditions. The first section focuses on the cat and specific considerations, covering topics from behavior and interactions to feline-specific pharmacology and analgesic considerations. The second section delves into patient care, including critical thinking, wound care, and bandaging. The third section focuses on diseases and conditions of the feline body systems. The companion website offers study questions for each chapter, educational tools, and clinical handouts, providing study materials and clinical tools for readers.
The book is a result of the collective effort of a group of phenomenal veterinary technician specialists dedicated to feline patients. Your devotion to this book as well as the profession inspires me to continue to grow and reach for the stars. It has been my honor to work with you all.
Paula Plummer
As I sat down to write this portion of the book, I quickly realized how challenging this page would be. I took a moment to reflect on my years as a credentialed technician and I am reminded of so many people that I not only consider a friend but family. So many people have touched my life and helped shape who I have become not just a technician but as a person. There are a few that I want to recognize a little more formally.
First and foremost, I give all the glory and recognition to God. His grace has provided me with this extraordinary life and has made endless opportunities possible. Reflecting on my career, I realize that many mentors were strategically placed in my life at pivotal points, guiding and shaping my professional journey. I am forever grateful to each of you for generously sharing your knowledge and unwavering belief in me, providing constant encouragement to reach for greatness.
To my husband, Josh, thank you for years of constant support and encouragement to reach for the next dream. I call myself blessed to walk through this life by your side. And to my family and friends, your constant presence in my corner is not just comforting, but inspiring.
Without the dedication and hard work of all the contributors and the publishing team, this book would not have been possible. I extend my heartfelt gratitude to everyone involved for bringing this cherished dream to fruition.
Feline Medicine for Veterinary Technicians is accompanied by a companion website.

Cats share behaviors with other species and have unique feline behaviors.
Emotions impact feline welfare and quality of life.
All animals learn via essentially the same mechanisms.
How cats sense and perceive the world impacts their behavior inside and outside the veterinary hospital.
Recognizing normal and abnormal behavior positions professionals to help clients and facilitate a healthy human–animal bond.
Understanding the learning theory is essential for veterinary professionals.
Screening for common unwanted behaviors should be part of every veterinary visit.
Incorporating behavior into every visit improves the lives of both cats and people.
The three most common cat behaviors that clients describe as problematic can sometimes be prevented or reversed.
Early detection improves the prognosis for treating problematic behaviors.
It is not necessary to know everything about behavior modification to provide early detection.
Building a referral community allows rapid referral when indicated.
All animals share certain behavioral traits and also have unique species-specific behaviors. Essentially, most animals learn through the same mechanisms. They acquire behaviors and abandon behaviors based on whether the behaviors are effective from the individual animal’s point of view. Emotions impact the animal’s overall experience, future decision-making, and even affect how memories are stored in the brain [1, 2]. To fulfill our vocation as veterinary professionals, we need to take time to understand the behavior of our patients: how they learn, how species are unique, and how they are similar. Differentiating between normal and abnormal behavior, anticipating how an animal will respond in a given situation, and knowing how to modify or change behavior are all crucial skills for veterinary professionals [1, 2]. In this chapter, we discuss how cats are similar to other species and how they are unique.
The human–animal bond is the heart of veterinary medicine. How animals behave can have a dramatic impact on the quality and length of the human–animal bond. A strong human–animal bond protects the physical and emotional health of cats. When we take the time to understand feline behavior, we can be good stewards of the human–animal bond. Caring stewardship improves the welfare for both pets and people [2, 3].
Animals are equipped with a sensory system that gathers information from the environment. Sensory information is transmitted to the brain, where it is decoded. Decoding sensations into useful information is called perception. Senses drive perceptions and perceptions impact behavior. Cats share similar senses to other mammals, including sight, olfaction, hearing, tactile (touch), and taste. How cats sense and perceive the world is unique, and understanding their special sensory organs and perceptive abilities allows veterinary professionals to provide the best possible care.
Sounds are measured by their frequency, measured in hertz (Hz). Cats have very sensitive hearing, with an approximate range spanning 55–79 000 Hz. For comparison, dogs hear frequencies between 67 and 45 000 Hz, and humans can only hear 20–20 000 Hz [2]. Cats are born with their ear canals closed and incompletely developed. As their ears open between 7 and 14 days of age, they begin to sense and perceive sounds in the environment [1]. Much like humans and many other mammals, as cats age and the hairs inside the inner ear stiffen, they will not hear higher frequencies as clearly [2]. Individual variation occurs, and some cats may be entirely deaf for part or all of their lives. Many of the sounds cats make are accompanied by a tactile experience. Purring is a good example. Neonatal kittens and deaf cats can perceive purring and will express vocalizations even if they cannot hear themselves [1].
When working with cats, providing an environment free from loud and shrill sounds will help them be more comfortable. For training purposes, a marker sound is often useful. Hospitalized cats should not be housed near equipment with high-frequency emissions, such as ultrasonic scalers or cleaners, as this may cause undue stress even though human caregivers are not able to fully hear these sounds [2].
Olfaction, or sensing and perceiving odors, is an important part of the lives of cats and how they communicate. When odor molecules enter the nasal epithelium, they will encounter olfaction centers that transmit this information to the olfactory bulb in the brain. Humans have about 5 million receptors. Cats have 150–200 million [2]! Cats spend a similar amount of time as dogs investigating odors in the environment. Odors that seem pleasant or mild to humans can be quite strong to cats, and potent chemicals and cleansers can cause “nose blindness” [1]. Nose blindness is when the olfactory center is temporarily overwhelmed by strong or noxious information. Being nose blind is uncomfortable for cats because it limits their ability to scan the environment for odor in a normal way.
Pheromones are another means of chemical communication for cats. Individual species have their own pheromones, and they are unique and specific to a given species. For example, humans cannot detect dog pheromones, and dogs cannot detect cat pheromones. Fear pheromones from a dog will not prompt a fear response in a cat, but fear pheromones from another cat may [1]. Pheromones are sensed by the Vomeronasal Organ or VNO. The VNO is considered part of the olfactory system, but pheromones and odors are different. Cats deposit pheromones in the environment via glands in the paws, cheeks, chin, mammary glands, anal gland secretions, and urine to share information about age, health, sexual and reproductive status, territory, and social interactions [1]. Synthetic pheromones simulating the F3 fraction deposited by facial rubbing can sometimes have a calming effect on cats. Many cats prefer and enjoy petting and touching the areas where the facial glands are located [4]. Figure 1.1 shows the locations of facial glands in cats.

Cats are very sensitive to both contrast and motion, but the spectrum of colors they see is far smaller than that of humans and dogs. Cats’ eyes have about 10% of the number of color receptors found in human eyes. Because they have tapetum lucidum, cats have superior vision under low light conditions [2].
When training cats, consider using high-contrast items for treats, targets, beds, scale pads, feeding stations, and toys. Moving toys are often more exciting to cats as a reward than stationary items.
In the veterinary setting, many of our patient interactions involve touch. The density of nerve-ending distribution over the body affects how intense a sensory input when it reaches the brain. Individual variation will determine how each animal processes and responds to touch. Take the example of tickling: touching a ticklish person and a non-ticklish person in the exact same way produces two very different responses [1, 2, 4]. This is due to individual variations in how the two different brains perceive similar raw sensory data. Perception drives behavior.
Similar to humans, dogs, and many other mammals, cats have a higher density of nerve endings around the face, lips, ears, paws, and genitals with the trunk having a lower density of nerve endings per square centimeter of surface area. Cats also have special sensory hairs (vibrissae) on their lips and cheeks, chin, above their eyes, and on the caudal aspect of the forelimbs above the carpal pads.
When planning touch for cats, consider how they experience these sensations. Starting touch in a less sensitive area and gliding to a more sensitive area is a good general practice [1–4]. For instance, if touching a forelimb, begin touching the back of the head or shoulder, then glide down the limb and avoid putting excessive pressure on the vibrissae. Many cats enjoy tactile stimulation around their cheeks, head, and rump areas. Pleasurable tactile stimulation is often a valuable form of distraction and reinforcement when interacting with and training cats. Actions such as tapping a cat’s head should not be used as a distraction, because it relies on an unpleasant or annoying sensation in a very sensitive area of the cat’s body.
Cats have about 500 taste receptors, while most humans have between 4000 and 9000 taste receptors [2]. Olfaction and taste are closely linked, and the palatability of food often relies more heavily on odor than flavor for cats. Based on anatomical studies, it is believed cats detect savory and bitter and show a decreased response to salty and sweet. Cats are somewhat unique in their propensity to develop rapid conditioned taste aversion. Just a single experience triggering an unpleasant taste response can lead to a cat showing extreme behavior when presented with the same odor (predictor of taste) in the future [3]. This can be particularly problematic when administering medications, and formulations should be considered with this behavioral need of cats in mind [2].
Animals rely heavily on body language to communicate their thoughts and feelings, and to broadcast their intent about upcoming actions or behaviors. Veterinary professionals can carefully observe feline body language to provide the best possible veterinary experience, help cats participate in training and conditioning programs, and assess responses to behavioral therapies.
When first learning the body language signals of cats, it can help to evaluate each body part of interest, and then consider the whole picture and the context before arriving at an interpretation. Since cats do not share our human language, we will never be able to ask about their precise intention, but through careful and repeated observation, we can anticipate the likely sequence of a cat’s behaviors based on their body language.
Arousal refers to the overall emotional state of readiness to act or react [2]. Cats experience enhanced arousal when they are excited, pursuing prey, playing, greeting friendly people or animals, or participating in fun activities. Arousal is also increased during times of stress when the fear response has been activated and cats must respond to a perceived threat or conflict. Evaluating the overall context of the observed behavior helps guide the interpretation of a cat’s body language. For instance, when pupils are mentioned, consider the ambient light. Dilated pupils can be a sign of stress, or dim lighting [1]. Context matters.
A calm or relaxed cat will express a low level of arousal and will appear comfortable. The cat may appear neutral or solicit interaction. Sometimes, these signals are referred to as distance-decreasing signals because they invite interaction.
Pupils
: Appropriate to ambient light.
Eyes
: Open and attentive or squinting with slow blinking, may hold prolonged eye contact if something is interesting.
Brows
: The muscles between the eyes are relaxed, creating a soft or neutral brow.
Ears
: Muscles around the ears are relaxed and the ears are held in a neutral or slightly forward position.
Lips and whiskers
: The commissure is relaxed, the whiskers are neutral and positioned to the side.
Body tension
: The cat’s muscles are largely relaxed. If lying down, often the cat will be stretched out or rolled on a hip. If walking, the cat will cross open spaces and appear free in its movements.
Tail
: When walking, the tail is held up and the tip is often curled over. Tail movements are fluid with relaxed muscles.
Proximity
: Will approach or will not move away when approached.
A cat experiencing mild-to-moderate stress will appear more aroused and settle less frequently. The cat may solicit interaction, but its body language when soliciting will appear more tentative. Mildly or moderately stressed cats may appear ambivalent, as though it is difficult for them to decide if they wish to approach or would prefer more distance.
