Current statistics indicate only 2 or 3 of the kittens in the picture will be adopted - the others will be euthanized because there are not enough homes. The answer is not more more homes, but fewer kittens (and puppies) born into a society where there are just too many already!
Being kind to animals is more than just an idea. It's a way of treating them with respect and encouraging others to do the same. That would include making sure that our own pets are spayed or neutered to help prevent the problem of pet overpopulation.
