Any other pitty mom's out there? We've got our 6 month old Rebel who I call a horse and my Ninja who is only 12 weeks old now. I'm so worried that she's too small! She's a razor edge pit so my boyfriend says she's supposed to be small I'm just worried. She is smaller than all of my cats and 1 of then is only 8 months old! Any other pit enthusiasts with advice/ input? Thank you!
