My Honest Positive/Negative View From My 3 Cats. Different Sizes & Ages. Indoor Cats.
Color: Dark gray, Size: 23"L x 15"W x 1.5"Th
POSITIVE: My cat likes the mat; it's very soft & keeps her content & warm. NEGATIVE: It slides very easily even though there's a grip fabric on the bottom, it's only sewn around the edge so it doesn't stop it from sliding. My senior cat did slip off it & fell. She won't go near it. She was limping for a little bit. I hand sewn a few spots in the bed to connect the top & bottom more securely. Cats didn't like or try to use it until I put a couple toys and some catnip then one of my cats was willing to lay on it. I also wish there was padding on it. I put in on her blanket so it could be more comfortable to sleep & feel secure. I don't know why they don't like the smell of it, but I hope with time, my cat will have her scent on it enough where it becomes her favorite bed.
