Read the following article and answer the question.

I took a nap on the couch with Forrest , who was tuckered out from playing with the kids nonstop . Apparently that 's what we need to calm the kitten down - a 6 year old and a 2 year old ! And since we had put Soft Claws on both of the cats a few weeks ago , I did n't have to worry about either of the kids ( or us ! ) getting scratched while they were playing .

What may be the reason for putting Soft Claws on the kittens ?
They wanted to protect their children .
