7 Signs Your Cat Needs a Vet Visit
Cats are experts at hiding pain and illness — it’s an instinct they inherited from their wild ancestors. By the time your cat shows obvious signs of distress, the underlying issue may have been developing for a while. Knowing what to look for can help you catch problems early, when they’re most treatable.
Here are seven signs that your cat may need a trip to the vet.
1. Changes in Appetite or Water Intake
A sudden increase or decrease in eating or drinking habits is one of the most reliable early warning signs. If your cat stops eating for more than 24 hours, or is suddenly drinking significantly more water than usual, it’s time to call the vet.
Increased thirst can point to diabetes, kidney disease, or hyperthyroidism — all common conditions in older cats.
2. Unexplained Weight Loss or Gain
Gradual weight changes can be hard to notice, especially in long-haired cats. A loss of even half a pound in a 10-pound cat is significant (that’s 5% of their body weight). Regular weigh-ins at home can help you spot trends early.
Common causes of unexplained weight loss include:
- Hyperthyroidism
- Diabetes
- Kidney disease
- Dental problems
- Intestinal parasites
- Cancer
3. Changes in Litter Box Habits
The litter box can tell you a lot about your cat’s health. Pay attention to:
- Frequency: Going more or less often than usual
- Straining: Spending a long time in the box without producing much
- Blood: Any pink or red tint in urine or stool
- Diarrhea or constipation: Lasting more than a day or two
4. Hiding or Behavioral Changes
Cats that suddenly start hiding, become less social, or show personality changes may be in pain or feeling unwell. While some behavior changes are normal (like stress from a new pet or move), persistent withdrawal is a red flag.
Watch for:
- Hiding in unusual places
- Aggression when touched in certain areas
- Loss of interest in play or interaction
- Excessive vocalization or unusual silence
5. Vomiting or Diarrhea
Occasional vomiting (like a hairball) can be normal, but frequent vomiting, vomiting with no hair, or vomiting combined with other symptoms warrants attention.
6. Changes in Grooming Habits
Cats are meticulous groomers. If your cat’s coat looks unkempt, greasy, or matted, it may indicate they’re not feeling well enough to groom themselves. On the flip side, excessive grooming (especially in one spot) can indicate skin issues, allergies, or stress.
7. Bad Breath or Drooling
While cat breath is never minty fresh, a noticeable change in breath odor can indicate dental disease, kidney problems, or other internal issues. Drooling, pawing at the mouth, or difficulty eating often point to oral pain.
When in Doubt, Call Your Vet
You know your cat better than anyone. If something feels “off” — even if you can’t pinpoint exactly what — trust your instincts. A quick phone call to your veterinarian can help you determine whether an in-person visit is needed.
Early detection saves lives, reduces treatment costs, and helps your cat live a longer, more comfortable life.
