Cat play is healthy. It replaces what we sometimes take from our cat - hunting for prey. Play is also healthy for people for a different reason.
Physical play is good for a cat's mental and physical well-being. I have always been concerned for full-time indoor cats.
Play for these cats is particularly important as they can become bored and develop behavioral problems.
I think full-time indoor living without adequate stimulation through play can cause health problems based on stress.
A cat's environment if it is a full-time indoor environment needs to be enriched. This usually takes the form of cat scratching posts, cat condos etc., cat window seats and cat toys.
Cat play is both mental stimulation and exercise for the cat.
The Fling-ama-String is a particularly good cat toy provided you use rechargeable batteries! If a cat likes the toy, and lots do, the batteries will run down fast. Get rechargeables. There will still be a cost but it is probably worth it.
Getting a cat to play with a toy can be a problem. The Fling-ama-String is said to be particularly attractive to a cat.
It gets good Amazon.com reviews: 68 reviews awarding four stars. That is good but please be aware that sometimes reviews are paid for.
