First, only one of my cats liked this stuff, so it was a royal pain to get them to swallow it. Most of the time, they spit it out. Second, I did see improvement with the frequency of hairballs, but not much.

Pros: Helped with the hairballs

Cons: not much though

My cats like pretty much everything. They like this as well. They will even eat it from the tube.

Pros: They like it

Cons: none

This stuff used to work great for my cat. I'd put it on my finger or on his nose, and he'd lick it right up. The only problem I had was remembering to give it to him.

Pros: easy to feed and works

Cons: I forget to give it?

I bought this product and it got rid of my cat's hairball problem right away! She loves the taste and is happy to lick it right off the tube or off my finger.

Pros: easy to feed, diminished my cats hairball problem

Cons: bad smell

One cat likes salmon flavor and one cat likes malt flavor. They eat it off the end of the tube. Walmart is a lot cheaper than the grocery store.

Pros: easy to feed

Cons: None
