It is still cold. I put a rubber pad on my cat, but why do I have many small ni bugs? It's not a cat.

If the cat is a stray cat or the owner doesn't clean the house, it is very likely that the cat will be infected with parasites. Cats shake these parasites out of bed when they scratch their hair while sleeping.

When the owner finds bugs on the mat, he should soak the items on the bed in boiling water in time, then soak them in disinfectant, wash them and expose them to the sun.
