I like both. But if I had to pick, it’d be cats.
The reason is that many people around here don’t handle their dogs well. That results in noise (hysterical barks in some cases) and poo landmines you have to watch out for.
Well-trained dogs? Appreciate them. Dogs I personally know? Good boys! Random dogs from the neighborhood? No thanks.
Having owned both, cats and dogs are quite different, and great in their own right. Dogs as a trusty companion, cats as a peculiar room mate.
I tried that for quite a while but ultimately gave up. For many (technical or non-English) topics, I found no fitting result of my search on the first page.
