Certainly. So what should humans do about the cats?

In practice it seems bring them snacks and put them in cute sweaters.

Spay/neuter your pet. It's the most effective thing to do.

I did some back-of-the-envelope math a while back that showed that if we wanted to make demand-of-pets match the supply-of-cats-and-dogs in the US, we'd basically each have to have one pet, at all times, for our entire lives. So, a family of four would need four pets. New baby: additional pet. Pet dies: get a new pet. One for each person at all times.

Barring that, if you want to minimize suffering of future stray cats/dogs (or limit environmental impact), it makes sense to do a one-time massive nationwide effort of scooping up all stray cats and dogs, and either spaying/neutering them, or culling them.

Get out of the way and let cats solve the problem! We're the problem, let them solve us!

I love comments like this for reminding me to do something more productive with my life.

Allow people to own dogs? I know where I live, many pet-owners who could have gone either way choose a cat just because there are almost no landlords who allow dogs.

Probably just have fewer cats

It seems this thread is filled with defensive cat-lovers who have no argument other than to bury heads in the sand.

Cat loving is known to be related to toxoplasmosis. Kitty-kitty!
