I have a bit strange question. My ratties alsmost never brux anymore. I spoil them to bits and they have everything they need. Plenty of space, cagemates, huge and clean cage with lots of toys, hammocks, shredding paper and climbeys, complete rat blocks supplemented with veggies and a piece of fruit or other snack every now and then... They get to play in my living room almost every day and receive plenty of snuggles. They look healthy and active and come running whenever I am near. As soon as I have a slight suspicion one might be sick I take them to the vet. So why don't they brux? Are they simply not bruxers or am I missing something they need to be happy?
