I have two bunnies, Snow and Bear; Female and Male respectively. When I came home from work, both of them were active and lively like always. I bought new hay(carefresh) and gave them more since they finished the last of the hay when I returned. I let them out before I headed back upstairs. I worked on homework for a little under an hour, maybe less than 45 minutes. I returned back down and Snow is hiding and isn't answering to the pellets except her brother, Bear. I brought them back in their cage and I started force feeding Snow Critical Care, pineapple, and water. Snow went through GI Stasis two times; the first time was very minor and a few doses of pineapple juice unforced helped. The second she didn't eat in less than 24 hours but over 12 hours; after a trip to the vet and got a prescription, she got better in a day and continued meds until it finished. But now I have no idea how she is suddenly acting sick AGAIN! Ever since Snow went through GI Stasis the second time, Snow and Bear have been on a strict Hay and (fiber based) Pellets Diet. I use Oxbow Young Adult Rabbit Pellets since they are only 11 months old.
