Hi Everyone,
We have a male minilop, 1.5 years old who is a house bunny and is out in the living room free to roam between 1800 and 2300 every day and lots at the weekend. We give him attention thoughout the evening by getting on the floor and massaging him, scratching his head, and he gets taken out for some sprinting in the long hallway for a bit. He always has hay and pellets and has spinach for dinner too and porridge for breakfast.
He is generally a very happy bunny, jumps up on the sofa a lot, loves attention and has attitude 
Recently however he has been doing a very odd thing. He starts by licking his front left leg and at some point grabs his hair and stands himself up whilst having his fur in his mouth so that he pulls it out. He then proceeds to eat this fur.
I’ve read a lot about female rabbits doing this to build nests but he is male, was neutered and is eating it.
I have looked for flea dust but can’t really see anything, all looks pretty white and clean. He also gets a fair amount of attention.
He recently moulted but has slowed down. He didn’t do this when he was moulting lots as you might think, he is doing it now when he is moulting not so much.
He doesn’t do it constantly but maybe once or twice an hour during his preening. Is this just a part of normal preening? Never seen this before.
Very puzzled and generally concerned as I don’t want him needing a stomach operation to remove matted fur.
Thanks
