I was feeding Maisey, and I was going up the stairs, she started meowing, then chased after me. Her tail was all puffed, teeth bared. She bit me hard on the thigh. I went into the bathroom, closed the door. I cleaned off the wound and put some first aid cream and bandaid on it. She seemed to be settled down. I've just never seen her like that and am scared. I did have some music on and she was perking up her ears and jerking her head to hear it as she was eating. When I put her cat lax on (I rub it onto her fur so she'll lick it off), she growled a little which she never does. I was wondering what I should do - should I isolate her? I think she's ok now, though. She doesn't seem in pain or anything. I'm scared to go near her. I've heard of this happening out of the blue - a woman recently posted about this, and took the cat to animal control. What should I do? It was a pretty deep bite, but it doesn't look that bad...
