Why purchase liners for your cat's water or food dish? Just use ceremaic or stainless steel and wash the dish once in a while..they are easy to clean.

Pros: none

Cons: unnecessary

I had one of these back in the no so many cat days and it was awesome for feeding canned food. You just pick the paper liner up and throw it away. No need to soak the bitty pieces off before they go in the dishwasher. You can also fix the food in the paper bowl and then put it in the holder, no need to put the bowl on your counter. I am a fan!

Pros: no wasing needed

Cons: getting replacement bowls

These might be good for traveling and/or wet food, otherwise they seem kind of a waste iof money. Whatever happened to hot soapy water?

Pros: Might be good in some situations

Cons: Wasteful
