Personality change / refusing touch in cats: what to do

A friendly cat suddenly aggressive or evasive — rule out pain and thyroid problems first.

What are the common causes?

Stomatitis / severe periodontal disease

See a vet within 24 hours

Severe oral inflammation makes cats refuse food, drool and paw at the mouth — needs professional dental care.

Degenerative arthritis

Home monitoring

90% of cats over 12 show X-ray evidence of arthritis — feline pain is extremely well hidden.

Stress / anxiety-related behavior problems

Home monitoring

Moving, new pets or visitors can trigger hiding, soiling and over-grooming — but rule out medical causes first.

FAQ

Is personality change / refusing touch in cats serious?

It depends on the combination of symptoms, how long it has lasted, and your pet's energy and appetite.Note that it can appear in problems that need prompt care, such as Stomatitis / severe periodontal disease. Enter the full symptom combination in our symptom checker for a more specific urgency assessment.

Can I monitor at home first? What should I watch?

If energy and appetite are normal with no other signs, 24-48 hours of monitoring is reasonable. Keep notes on frequency, duration, appetite, water intake, energy and what the stool/urine looks like — vets find this very useful.

What should I prepare before the clinic?

Note when the symptom started and how it changed; bring packaging or residue if ingestion is suspected; bring vaccination and deworming records; and if possible take a video (odd gait, cough sound) — clearer than describing.
