I just put the clear ones for kittens on my Oreo (about 10-12 weeks old.... I think, does that sound right?) anyway- I love them because now I am able to not worry about her sharpening her claws on all the wrong places (even though I bought and showed her all the right places) but she hates them...
I have a little kitty that as soon as I got I set up house in my house, and then 2 miles away at my grandparents- I spend about equal time at both places, she has her own litter box at both houses, and seems ok about the road travel...
I was thinking about buying one of those cute travel bags...
