Yes, cats can experience significant stress, anxiety, and behavioral changes after surgery, sometimes appearing traumatized due to pain, disorientation from anesthesia, unfamiliar handling, and the stress of recovery, leading to hiding, aggression (hissing, swatting), vocalizing, or loss of appetite, though most typically return to normal with proper care and time.
Occasionally after surgery, cats and kittens can have an adverse behavioral reaction to anesthesia. Behaviors you may see include, but are not limited to: hissing, growling, and swatting and may be towards people or other animals including their family members.
Nearly every new Tripawd parent reports that their cat's behavior during the first few nights after surgery includes rapid breathing, more vocalizing, anxiety, inappetence (refusing to eat) and just acting weird. Many cats may seem depressed and become constipated, sometimes for up to a week.

Trauma can also manifest as “shaking, hiding, urination and/or defecation when the trigger attempts to interact, howling, pacing, excessive vocalization, and panting,” says Pia Silvani, director of behavioral rehabilitation at the ASPCA's Behavioral Rehabilitation Center.
This may result in reactions such as hissing, growling, swatting, and scratching. Your cat's behavior is usually caused by feeling disorientated after the anesthetic and being extra sensitive and vulnerable. It may also be a sign they're in pain. Your cat may also be more stressed and anxious than usual.
You should be concerned and should contact the hospital immediately if you see any of the following at the surgical site: Continuous or excessive blood draining. Intermittent blood seepage that continues for more than 24 hours. Excessive swelling or redness of the skin.

How to reduce your cat's stress
If your cat has gone through a harrowing experience, they might feel like they need to be on the defensive all the time in order to be safe. If you find that your cat is particularly aggressive, clawing, scratching, pawing or biting, this is an important note to discuss with your vet since it may be a sign of PTSD.
Cats do remember negative experiences, but they don't dwell on resentment the way people do. Instead, they react based on learned associations and their need for safety. With patience, consistency, and care, most cats return to positive behaviors quickly.
The number one killer of cats depends on age and lifestyle, but cancer is the leading cause of death in older cats, while Feline Leukemia Virus (FeLV), accidents/trauma (especially for younger cats), and diseases like kidney/heart issues are major factors, with FeLV often cited as the top infectious killer. Causes range from diseases like FeLV, Feline Immunodeficiency Virus (FIV), and FIP, to organ system failures (kidney, heart), and external factors like poisons or trauma.
Cat behavior red flags signal potential medical or emotional issues, including sudden changes in eating/drinking, litter box problems, excessive vocalization, increased hiding, aggression, lethargy, or changes in grooming (like overgrooming or stopping). Because cats hide illness well, any significant deviation from their normal routine, such as increased thirst, appetite changes, or unusual hiding, warrants an urgent vet visit to rule out serious underlying conditions like kidney disease, hyperthyroidism, diabetes, or pain.
Signs That a Cat or Dog Has Experienced Trauma
To apologize to a cat, use a soft, calm tone, offer treats or toys, initiate slow blinking, give space if needed, and respect their boundaries for physical touch, focusing on actions and tone over words to rebuild trust and affection. Don't force interaction, as they respond to reassurance and positive experiences more than human language.
While it's true cats' short term memory can hold onto events for up to 16 hours, and remember traumatic associations for a lifetime, cats are not "holding a grudge" out of spite, but rather protecting themselves from negative experiences.
Valerian Root
It works by stimulating the release of gamma-aminobutyric acid (GABA) in the brain, a neurotransmitter that helps reduce stress and promote a sense of calm. You can offer valerian root to your cat in various forms, such as dried root, tea, or even as a stuffing for toys.
Symptoms of stress
You can tell if a cat is sad by noticing changes in their behavior, like loss of appetite, excessive sleeping or hiding, poor grooming, increased vocalization (especially mournful cries), changes in litter box habits (urinating outside the box), or showing uncharacteristic aggression or clinginess, as these often signal unhappiness, stress, or illness. Always consult a vet, as these signs can also point to medical issues.
