I just recently noticed while playing with my rat that her nails are SHARP. Do I need to trim them? Or do rats have their own way of trimming their nails?
In my experience, stones or bricks in the cage just turn into something to pee on. You can use a small pair of nail clippers and just take the tips off the nails. Be sure to have Quick-Stop or something on hand in case you cut the quick.
Yup, I had a set of nail clippers that were just for my ratties. I also had a little nail file to smooth them out too. She would let me gently file her nails while watching T.V. )
