When a short-haired cat with a key color appears to sit, stretch its hind legs forward, and rub the ground with its anus, it may be due to parasitic infection or inflammation of the anal glands, causing the short-haired cat with such a weird behavior. In addition, if there is persistent watery diarrhea, the area around the anus will be inflamed, red and swollen, causing itching, and the short-haired cat with key color will also rub the ground.

In addition, if the key color short-haired cat suddenly becomes thinner and loses weight even though it eats normally, it may be because the key color short-haired cat is suffering from parasites.
