My bunny, Loki, has just returned from a relative’s house. Usually when we bring him home from a different house after a couple of days, he is the happiest bun in the world, (flops, binkies around the house, etc.) When we brought him back this time, I had a friend over for 2 nights. Loki hates it when people come over, and he bites them like crazy. The friend has left 2 days ago, and he is acting weird. He won’t eat his carrots, but he is eating hay and pellets, but he is eating junk. We have an old quilt underneath his X-pen, and he tore a big hole in it and ate the stuffing out of it. I went in there yesterday and laid down, and he jumped on my back like he always does and ripped a big hunk of hair off of my head and ate it. I didn’t know what was going on until I saw the ends going into his mouth. We have a runner under his cage (made of storage cubes) and it is rubber with loopy fabric on top. He crammed himself behind the cage and ate a big piece of that. He has been angry and is not afraid to bite. He pees all over the place, but he is a neutered male and we got him neutered at least 3 months ago. He is turning 1 in January. Please Help!
