My bunny is acting strange.

Question
my bunny has been acting strange, it is laying down a lot and seems to not be hopping at all. it will not eat anything. it hasn't pooped at all today,it hasn't drank any water today. he also seems to be breathing heavily,his stomach goes up and down quickly.he also lets you pet his stomach when before all this he would hop up before you could touch his stomach at all.i have read about this and i heard it may be a blockage, will the blockage pass? or will i need to see a vet right away, and could he last a few days like this?

Answer
It sounds like Gastrointestinal Stasis, which is where the gut stops moving properly. It is one of the leading causes of death, and you need to get your rabbit to a vet right away. If you have an emergency rabbit vet, you should get him there as soon as you get this message. If not, get him to one as soon as a vet opens.
