Yeah but there's lots of cat owners who want to read about cats and (speculating) cat health diet and behavior and maybe show cat photos and talk cat.

Build a website for them and do the cold calls to cat food suppliers to sell ads.

Or sell websites to cat owners for their cat - every cat needs a website.

Or make "hot or not" for cats.

Or combine all these into one site.

The internet was mostly made for porn and cats so you should be able to get the cat thing to work.
