If your cat isn't feeling their best, they will show subtle changes in behavior and energy level, but these small changes can be hard for pet owners to notice. For this reason, it is important to keep a close eye on your cat's health so you can spot the signs of common and serious cat illnesses.
Is my cat sick?
Much like people cats can suddenly find themselves feeling sick. Cat illnesses range from common and highly contagious cat colds (upper respiratory infections), to diabetes, feline immunodeficiency virus, feline leukemia virus, worms, hyperthyroidism, and even cancer.
Of course, the symptoms that your cat shows will depend upon the kind of illness they are suffering from however there are a number of symptoms that are common to many health issues in cats.
Below our vets from Rocklin Road Animal Hospital share a few signs that can mean it's time to book a vet appointment, as well as more serious symptoms that indicate that your cat is in need of emergency veterinary care.
