Dotoner Cat Post-Surgery Suit, Female/Male Cat Clothes, Wound Protection, Neutering, Nursing Wear, Skin Protection, Alternative to Elizabethan Collar 293909 Quoting the following review: "S size is suitable for small cats up to 2kg. It has some stretch, but the overall construction is small. Cat body types vary greatly, so a perfect fit is only possible with custom-made clothing. However, this product is designed with general sizing in mind, so some cats may find it too small or too large. My cat is 2.8kg, and considering the general sizing, I was worried about it coming off, so I ordered the S size. When I actually put it on, it went on because it's made of a stretchy T-shirt-like material. However, because it's constantly stretched, it seemed tight, and it might put a strain on the back and shoulders. Although it has some elasticity, it's only a slight amount because it's fixed at the seams. I used it for about four days, and it was still too small, so I switched to a larger size. As for functionality, it's perfect for the post-surgery wear that owners want, so I recommend it if the size fits. Especially, there's a lock to prevent the neck from slipping off the shoulders, so it stays in place without shifting. The back side is designed to hook onto the legs, but it doesn't interfere with the cat's rear, so they could use the toilet cleanly.
