I feel awesome walking around the house in these! I needed slippers to stay warm and these are perfect, plus they're so fun. I want to bring them everywhere like a little kid with their favorite toy.
My cat doesn't attack them which surprised me because she'll "fight" with other fake fur accessories I have. every cat is different on this though!
If you want these for a costume, the sole is only sturdy enough to wear around the house. You would have to attach a better sole on bottom (like flip flops or something) if you wanted to walk around outside. Or cut off the bottom and use it as a shoe cover.
But they are fantastic house slippers! I love them!
