It seems to be hard to find info on cats wearing diapers so I thought I would write a review. About 1 1/2 years ago My little man weighed 18lbs and was having health issues and ended up having part of his liver removed. He lost a lot of weight (He's still around 7lbs now) and unfortunately his meds end up with him having bladder issues and infections. After trying puppy pad training and failing with other suggestions, I gave up and got him diapers. They have been amazingly helpful. The disposable ones he wears only when his cloth ones are in the wash but, they are of good quality..absorb all his pee and amazingly fit his 6 inch waist. The little tape strips are re-adjustable in case you miss your mark the first time. :) The only thing I had issues with is the smell of the diapers themselves, they are a bit flowery/perfumy. I have asthma and allergies and the smell is a bit much for me. Over all, these work really well on my teeny, grouchy little man cat.
