Why is my rabbit having diarrhea?

I went to pick him up today and I realized he had a huge glob of poop on his tail and in his fur.
Its weird because normally his poop is little dry balls that dont get stuck anywhere and simply fall.but this is like mushy and stuck to his fur.Kind of like the same substance as human poop.It smells really bad too.
I've been making sure he has plenty of water to drink,thinking maybe he just had diarraeh from heat or somehitng.
I dont want to have to take him to the vet,but I dont know what else to do.

hey I think I can help you without having to go to a vet because I am a future vet... plus I have a rabbit. Well anyways its probably diahhrea. You need to stop giving him vegetables and fruit and all human food until it goes away. Just give him dry food. sometimes lettuce can give them diahhrea, and can lead to death. or it could've been that they gave him a different kind of food where he was at, and has to get used to the sudden change. don't worry about it because the same thing happened to my rabbit, but he's okay. if it gets worse or he has it for more than 2 weeks.. take him to a vet. I hope I helped you. you can trust me. bye!

earth hugger is probably right about the veggies...but I'd take him into the vet after 3 or 4 days of diarreah...Two weeks is WAY too long, as they dehydrate...

my rabbit has been having the same problem, but we are thinking its just stress because there is a baby in the house now.
so maybe if there is something new in your house that its not used to could also be a reason.

If you switch brands of food, feed it something its not use too like grass, fruit feed it small amounts my rabbit done it when I gave it carrots

Thats the same thing thats happing to me right know. And im just worried she might die. I just got her about 4 days ago and now she has it. shes only 9-10 weeks old. I cannt take her to the vet becuase I dont know how much it costs.if any of you guys now how much it costs to take a abunny to the vet (canadian money) please tell me because I really want to know how much it costs so I can take her there.
