Sick bunny with rumbly tummy

[Bville]

My bunny Smokey has been sick since last weekend. I took him to the vet on Monday and she gave him drops for an eye infection and subcu fluids because he had stopped eating, peeing, and pooping last weekend. I have been feeding him Critical Care all week. I took him back to the vet on Thursday and got Metoclompraminde to help get his digestion moving because I really wasn't seeing any improvement. He is basically the same, taking about 1 tbs. of Critical Care about 5 times a day, eating some greens and a few pellets on his own, will only eat a couple pieces of hay if I hand feed it to him, and just pooping a small amount once or twice a day. My question today though is that when I am feeding him his Critical Care, I hold him with one hand under his chest and I feel a rumbling for a few seconds every once in a while. I am wondering what this is and, of course, is it a bad thing or a good thing? It's kind of like his body trembles or rumbles a little bit and it seems to be coming from his stomach. Is it just the food moving through his stomach or something else?

It could have to do with the gut stimulant, but it's more likely to be gas. Could be from the meds or from the critical care. If he seems uncomfortable you could try giving some simethicone. If it's occurring frequently, you may want to add in some Benebac probiotics to try and help balance the guts microflora.

Do you know if it's okay to give simethicone with the Metoclompraminde? I'll have to wait until Monday to ask my vet unless someone else can tell me for sure.

As far as I know, it doesn't. It isn't absorbed, so is usually considered relatively safe. You do want to make sure to use one that doesn't contain the artificial sweeteners aspartame, sucralose, and xylitol.
