If you have a newly adopted cat, many behaviors you might brush over could be a symptom of a medical issue. Here are a few things to monitor in your new feline friend:
Activity Level: An older cat might not be interested in climbing or playing, but a kitten with a low activity level might be an alarm bell.
Appetite: For the first few days, a new cat might not eat much due to stress. However, kittens are not finicky eaters. Not eating at all is very dangerous for cats and could cause a fatal liver disease. If your cat’s appetite does not pick up after a few days, check with your vet.
Water intake: Cats don’t tend to drink a lot of water, so a cat seeking out water constantly might be anxious, or this might be a symptom of diabetes or kidney disease. A cat that doesn’t drink water at all might be not feeling well for a variety of reasons.
Bad Breath: Bad breath might be a symptom of gum disease or other dental problems. It could also be related to an infection, digestive disorder, or kidney disease.
