Because cats are carnivores, the incidence of renal failure is much higher than that of dogs, so professional cat food should be given under the guidance of veterinarians. Salivation is the most common in dental calculus and gingivitis, and the food intake is gradually decreasing. If you want to eat but don't open your mouth, you will gradually lose weight and have obvious bad breath. There are ways to prevent it. Eating dry cat food for a long time is helpful to gum health and delay the occurrence of dental calculus.
Obesity is the most common nutritional disease of old cats, and maintaining proper weight is the key to avoid obesity. Because cats' eating habits are quite fixed in their later years, it is better to give a small amount of palatable food regularly. Loss of appetite and weight loss are the common symptoms of hypothyroidism. You can feed high-energy and palatable foods, and cats should avoid long-term loss of appetite (especially fat cats) to prevent fatty liver.
Cats usually like to comb their fur with their tongues. Because they have barbs on their tongues, it is easy to swallow fur into their bodies, causing feces to accumulate in the colon. As a cat owner, we should pay attention to some changes in old cats, especially when cats are over 6 years old.
