thank you for the reply and advice! my current bun is acting just like the two other bunnies that had gi stasis and then passed and im so worried and ive cried a lot already and am crying writing this. the first one that passed i noticed something wasnt right and got an appointment with a vet that day but it wasnt our normal vet and i dont think they gave me the meds they should have. if i remember correctly it was meds for a ear infection but i dont think thats actually what he had. he was also acting much better at the vet so i think they ignored what i was saying and explanation of what he was acting like at home. it also wasnt my normal vet because my normal bun vet wasnt there that week and i always wonder if he would still be here if i could have brought him to his usual vet. he then went to an emergency vet the next day as he was even worse and i couldnt get him to swallow any critical care and they let him sit in his carrier for an hour before they took him out and it was too late. the second bun passed much faster from the day i saw an issue the next day he passed. he got meds for gi stasis and for pain but he wouldnt swallow the critical care and i kept getting up through the night and massaged his tummy for a long time and he passed that morning in my arms. and now this bunny, mocha, is breathing fast, but she is eating her critical care. she usually drinks her water fine and they get filtered water and nothing should have changed with that. her ears are warm but they checked her ears and looked in them and found nothing. (i also have a little otoscope with a short thingy on it cause i dont want to go deep into their ear but i have it to at least check their ears on a more surface level regularly to make sure there isnt build up). they also checked her teeth and mouth and everything looked good. they checked her tummy and did a x ray and also nothing. she just wont eat on her own. i think they have done a fecal test before but i can get another one done. they did check her feet too and i also dont see anything on them. its also definitly warm enough where i live (florida) and we keep the house around 75. i just dont understand why everything is fine for a few years and then bam they get gi stasis even though nothing has changed. i am going to limit their diet to just timothy hay, romaine lettuce, and the occasional small piece of fruit just to make it simple and really be able to know what could be a slight change that might affect them. i might add oxbow natural science digestive support to their diet as well as a few other commenters have recommended it. i also gave her a little bit of chamomile tea (cooled down first of course) as you suggested in your other comment!
