We got a cat a few days ago & he seemed so nice up until last night when he turned on my daughter and bit/scratched her arm. He pierced my poor baby girl's skin so I took her to the hospital & she doesn't have an infection but her arm is just in pain and is swollen as heck. I hate that my baby is hurting. 😟😢
