Adopted Arnold recently. He is a 2 yr old lionhead cross neutered bunny. He loves to eat hay. He also seems to drink a lot more water than our spayed female lionhead. I switched him from a dish to a bottle because he is kind of messy. He drinks so much his litter box is always wet. I have to empty and wash and dry it daily. He just saw the vet about two weeks ago for a well check, the day he came to live with us. Is excessive drinking something to worry about? Dont know if he is bored and drinks a lot because of that or has something wrong. He seems otherwise fine.
