I have not used them before. I just got two
females that are about 14 weeks old and I'm really starting to think about getting them some although they would probably tear them off each other's hineys.
I'm am having an awful time with them eating their potty pads (even though they are in the tray) and even eating their own poop.
It's like a race to see who can get to the poop faster!
You think they have anything for their mouths too?
Good luck and if you get them - I hope they work for you!
