My bunny, Bobka , has been with me since he was little (a rescue), he is now 9-10 years old. He has been very thirsty lately...water bottle fillups would be 3-4 times per week now he wants to drink that amount in 1-2 days plus water we keep in a bowl. He is drinking a lot. He is eating ok and going to the bathroom just fine. He seems to be more lethargic in the past few weeks and his spine is more pronounced (he is eating the same amount of food) so I dont know what this condition is called. I realize he is considered elderly. He is a neutered Silver Fox. He has always been a sweetie and is now becoming more attached to me than ever. He weighs about 13 lbs. I have also noticed lethargy when he has usually been playful with toys. Should I just accept that he is older and slowing down? The drinking seems to be the biggest issue. Any thoughts before I bring him to the vet...he gets very stressed in the car. Thank you for your time! :?
