Appetite loss. If your cat won’t eat for more than two days, that’s a concern. Appetite is a general indicator of health problems. This is especially serious if it lasts more than four to five days.
Dragging hind quarters on floor. This can indicate an impacted anal gland or problems such as kidney disease, diabetes, or pelvic injury.
Severe constipation/diarrhea or dehydration, blood in the urine or feces. These conditions all require examination. Seek medical attention.
Straining to urinate. This can indicate cystitis, bladder infection or, especially in male cats, urinary obstruction. If left untreated, a urinary obstruction can cause death within twenty-four hours.
Drinking increase. This can indicate conditions such as diabetes, kidney disease, and uterine infection.
Excessive salivation can be a sign of such problems as gingivitis, a viral infection, or poisoning.
Enlarged abdomen. If your cat is not large to begin with, this can indicate serious problems such as tumors, heart or liver disease. In kittens, a rapidly enlarging belly may mean intestinal parasites or feline infectious peritonitis.
Gasping or shortness of breath. This can be a sign of obstruction, heart or respiratory problems.
Lethargy, hiding, or low energy. Cats who aren’t acting like themselves may be signaling that they have health problems. Seek medical attention if your cat’s personality drastically changes.
Among other things, lumps can be tumors, cysts, or fatty deposits. They should always be examined by a vet, especially if they increase rapidly in size.
Red or swollen gums. This indicates gingivitis and dental disease. It can also indicate kidney or liver problems, feline leukemia virus, or diabetes.
Weight loss despite good appetite. This can indicate conditions such as diabetes, hyperthyroidism, and pancreatic problems.
Upper respiratory infection (URI). This is like a human cold. A cat with URI will have some or all of the following symptoms: sneezing, congestion, appetite loss, fever, runny eyes/nose, drooling, and lethargy. Although URI is highly contagious amongst cats, people and dogs are not at risk. A cat with URI requires veterinary care and prescription antibiotics. Most cats fully recover from this type of infection within one to three weeks.
Repeatedly licking the floor or wall. This can indicate an underlying health issue.
