We purchased these for our kitten, who was recovering from spay surgery. She absolutely hated the Cone of Shame and really had a hard time doing anything (eating, drinking, using her litterbox, etc.) with it on, so we needed a better option. These suits were the perfect option. Our kitty is between sizes (we bought med & large to figure out which one fit best), so we sized down to the medium. I will say there is a HUGE size leap from medium to large. If you aren't sure of size, buy both. The medium was a bit short in length overall, so it bothered her when she walked - no actual skin irritation - just annoyed her as it was snug under her back legs. However, when we tried the large, she "escaped" in minutes. So, we stuck with the medium - not a big thing for 2 weeks. We wanted her to slow down anyway to recover.Aside from the length issue, these were great! I honestly don't know why more vets don't recommend them. The suits are cute, well made, and very soft. They are (I believe) 100% cotton. We made the mistake of washing one of them in hot water and drying on high, and it is now comically small. So, wash in warm or cold, and air dry.Overall, I was very happy being able to provide a more comfortable recovery option than the cone, while keeping her safe (and happy). 100% would recommend.
