What is a Wool Block and GI Stasis?

A Wool block occurs when the stomach fills up with rabbit hair. Usually during a molt.
It can be a partial blockage, complete blockage, or just makes the rabbit feel full when it isn’t. Rabbits with wool block will not likely eat as much and as a result can lose weight. This can cause a lazy digestive system , constipation and gas build up.

Gas/bloating is very painful for rabbits. If a rabbit has gas/bloat it will be in a lot of discomfort, hunched up in it’s cage and likely grinding it’s teeth. A vet is recommended in this case, if you can’t get to a vet here is what I’d do. The stomach acid can’t break down or dissolve hair. Therefore I want to help the rabbit pass (poop) the hair out a little bit at a time. If the rabbit passes a large amount of hair all at once it can cause a complete blockage in the intestine. When a rabbit gets a blockage of hair, quite often the rabbit pellets and other food will bind to the mass. Just like a clogged sink drain full of hair, the food and solids will become trapped in it, this causes a larger mass. When I suspect a wool blockage here are some things I do; Pineapple juice (fresh ), Fresh pineapple, papaya fresh or tablets, to help remove the pellets and food stuck to the hair (clean the hair off). Some breeders use Meat tenderizer. I thought this really weird except they’re only using the pineapple enzyme based meat tenderizer (concentrated pineapple enzymes). There are other kinds, like tomato based and chemical based tenderizer’s so I don’t know why they just say tenderizer.

GI Stasis is when the normal movement of the guts slows or becomes static. This can happen when the rabbit stops eating for a number of reasons such as sudden weather change (extreme heat or extreme cold), illness, recovering from an operation, Poop ball, Stress, dehydration, etc.
