My cat rips up the carpet
I found a cat two years ago. He was about 4 months old. We had him neutered and chipped, and his shots are up to date. He stayed out all night and came back about 6 am, and stayed in until 10 pm.
The last two weeks, he doesn't go out at night anymore. He cries by the doors. We open the door and he runs, hiding under bed.
The bad part is he starts clawing and scratching up our carpets by the doors. He also has gotten more aggressive. We are at our wit's end.
