So, I have an eight year old Flemish giant rabbit, and am slightly concerned for him. He has not touched his water bottle in three days, he is an outdoor bunny and lately it has been very hot out. Today it was almost in the 90s, so he must need water. I've tried adding a bowl of water in his cage but he hasn't touched that either. I do have frozen pop bottles in his cage to help cool things down but that can't be enough to beat this summer heat, and the bunny hasn't even lost his winter coat yet, so shouldn't he be drinking a lot of water? What do I do?
