My bunny Gimpy hasn't quite been himself these past few days. I noticed he wasn't eating much of his hay, but I had bought him a bag of Oxbox(timothy & orchard) when his normal hay is a different brand. It sometimes takes him a day or 2 to switch over so his lack of hay eating wasn't too concerning. Plus I was still seeing him eat a little bit of it. Then about 3 days ago He started pooping a bit on the floor and a few pee spots. He's done it before and I had just changed his litter and clipped his nails so its not uncommon for his to protest by doing this. but it usually only last a day and then he goes back to normal. But thats not the case here. For 3 days he's poop and peed on the floor. He's still going into his litter box too. He's also not been eating all his pellets. I usually feed him before bed and by morning his pellets are gone. Thats how I can tell when something isn't right as he doesn't eat all his pellets. So for the past few days he's only been eating about half his pellets, and even left some of the oats I had mixed in, when normally the first thing he does is dig through and pick out all the oats. So today I woke up to him having peed in on his cardboard box and there was 3 spots of diarrhea. I noticed last night when I was cleaning up his poops that they were smaller and kind of tear dropped shaped too. He only ate a bit of his pellets over night. After I cleaned up his cage he did come over and have a big drink and ate a few pellets. So he is still eating a bit and drinking. He is moving around and seems alert. So what should I do to help him? I dont' want him getting sicker. He has been shedding a lot lately and with his lowered hay intake i'm a little worried. I'm going to go out this afternoon and buy him his regular hay and see if that helps. Anything else work for upset tummies? I tried pumpkin before and he wouldn't eat it.
