Feline abdominal transmission is caused by the mutation of feline coronavirus. Normal feline coronavirus will only cause diarrhea in cats, which can usually be cured on its own. However, mutated coronavirus can cause dry abdominal transmission and wet transmission in cats. As for why the abdomen mutates, there is currently no precise answer, but it is generally believed to be caused by stress.

Tip:

If we want cats to stay away from belly-to-belly transmission, we need to reduce their stress, bathe less, and not keep the stocking density too high, etc.
