I'm thinking about getting him a different bottle, as he HATES having a water bowl. I think some of the problem may be that he's not getting enough water out of the bottle when he licks the end, as he does drink from the bottle whilst he's chewing it..
I don't know if this will affect anything, but, he was brought up in a critter trail cage (
), and spent the first year of his life there, as he came to me as a rescue. So, with the water bottle in thr critter trail not having a ball in it, i wondered if that would affect him..
