We keep our bunnies button and Banjo on the front porch and when we came this morning around eleven to give them their morning lettuce and frozen ice jugs (it has been very humid and 90s every day), button would not take his lettuce. He let me pick him up which he never does. His brother is normal. He laid down next to his jug and was breathing rapidly. Ears not hot and not panting. He ate his feed last night. We immediately brought them inside and they have been inside for over an hour now. He is still not eating refusing, hay, critical care, feed, and lettuce which he loves. Sways a little when he moves. He also urinated and pooped (normal pellets) on the towel he was sitting on instead of using the litter box. Very worried. We called the vet. Should i force feed him critical care? Is this heat shock still? He is cool now and has an ice jug even though he is inside in the ac.
