First of all, judge whether you are healthy by your physical condition.
Actually, cats are just like people. When they are unhealthy, their bodies will show a series of discomfort, so the owner can judge whether the cats are healthy by their physical condition. When calling a cat, if the cat's ears swing back and forth, it proves that the cat is healthy, while some sick cats or deaf cats have little or no response to the sound. In addition, cats' mouths are often clean and will not drool. Once cats drool or their teeth turn yellow, they are likely to get sick, such as periodontitis. It should also be noted that the posture of cats' limbs is often normal when they walk. If the cat is lame, there is probably something wrong with the cat's bones. Take the cat to the pet hospital for treatment in time, so as not to delay the illness. When many owners play with cats, cats can actually react quickly, but if some cats react slowly or not, it means that this cat may have some mental problems. Cats love cleanliness, so they like to lick their fur. But if the cat suddenly stops licking, it is likely that the cat has some psychological problems, such as anxiety.
Second, judge whether the cat is healthy through diet.
Cats actually like to eat. If the owner feeds the cat cat food, and the cat's appetite drops or doesn't eat it directly, it is likely that the cat is not feeling well. It should also be noted that after eating cat food, most cats actually pull at least twice a day, but if the cat doesn't defecate for a day or two, it means that there are some bad conditions in the cat's body.
Finally, if the cat has a lively personality, but suddenly doesn't like to move and likes to sleep, it may be that there is something wrong with the cat's health.
