I think 9-lives products are wonderful. The fact that the new Morris the cat is from a shelter is outstanding. It's easy to support a company that endorses adopting from shelters.
My kitties love the food, and they have never had any complaints about the toys.
The oldest of my cats are a trio of 6 year olds, they tend not to play a whole lot. However, I bought these balls and my 7 yr old daughter played with them first. It made the cats curious and before I knew it, everyone was playing and skittering across the linoleum in the dining room.
I enjoy watching them, and laugh until my sides hurt.
I definitely reccomend giving these a try.

Pros: They bounce off the base boards and encourage the kids to play with the kitties.

Cons: They blend in to the carpet in the living room.

These are really cute and fun for the cats. The price is good also, but I have a mixed family dog and cat and these are just not the best choice for us.

My cat really enjoys the jump factor but of course the dog has to grab it too.

The ball is simply to easy for my Min-Pin to tear into shreds and I am concerned over a choking factor.

If you are a cat only family, I'm sure they would love them. But if you are like me and have both you may want to think twice.

Pros: Good price, cute and fun

Cons: Mixed animal home and not good for the dog

These are great to use to give your cat some much needed exercise. My cats batted them around, chased after them and even hopped and jumped when they were bounced. The only problem being my dog who was slightly jealous. I had to be careful that he didn't get any and choke on them. It was also great entertainment to watch the cats go crazy trying to catch them!

Pros: Great exercise for Cats

Cons: Too small for dog so need to be careful around him

My dogs and cats fight over these! There is always running and jumping when we take them down for playtime. The only problem I have found is between the cats back claws and the dogs teeth they don't last very long. However, I don't know if that could be considered a flaw as these are designed for cats and probably weren't tested adding dog teeth to the mix!

Pros: fun, easy to chase, smaller size

Cons: don't last as long as some balls

My cats and DOGS love these! But the dogs teeth really break them easily. My cats spends HOURS and hours playing with them, that is until the dogs take it away!

Pros: Bouncy, Fun, Enjoyable

Cons: Don't last long
