GI Stasis: This is probably the most common of rabbit ailments. It refers to the condition of a rabbit who suddenly stops eating. Such a rabbit won’t eat even his favorite treat. The danger is one that is difficult to remember, because it doesn’t seem a logical consequence. The danger is:
When a rabbit suddenly stops eating, his body temperature begins to fall, fairly rapidly. You can lose a rabbit to hypothermia in a matter of hours.
You need to determine NOW how you will restore or stop the drop in body temperature as you’re rushing your rabbit to the veterinarian. A hot water bottle, wrapped in a towel in the bottom of a carrier with the rabbit sitting on top of it is perhaps one of the best ways to do this. However, the microwave bags that can be heated, or even a bottle or jar with a good seal can be used.
GI Stasis is usually easily treated, but is deadly in a matter of hours, if the body temperature drops low enough.
Typical treatment includes adding heat to the rabbit (a bag with grain heated in the microwave is a good tool for this), motility drugs, warm sub-cu fluids, simethicone if there is any bloating, and of great importance if there is pain, pain medications. Getting the rabbit to hop around and syringe feeding a mush (such as Critical Care or Angel’s Mush) can also help.
