Unfortunately, cats breed almost like bunnies, and dogs are not far behind. Indiscriminate breeding in the face of lack of natural predators means hundreds of unwanted animals to roam the streets sick, hungry, and lame until they are hit by a car or starve or die from distemper or FIP or FLV.
Folks who are not serious hobby breeders should be encouraged to neuter and spay. Benefits include no roaming, spraying, fighting, etc. Females who are spayed have lower rates of cancer and do not die of pyometritis.
And since animals live in the "now", unlike humans, they do not have regrets for what they do not miss. While we all enjoy anthropomorphizing our pets, they DON'T think like humans . . . as most good pet owners have figured out already.
