I could never choose between dogs and cats, except to say that cats are easier as far as finding a place to live if you don’t own a home. I would not be able to live without having both I’m pretty sure, but definitely not without cats. My pets mean the world to me and consume my life.
Having said that, I also try to do animal rescue around my neighborhood. Over the years, I’ve picked up multiple dogs off the streets (including my current three dogs), and I take them to the shelter or a rescue group if possible. I’ve had to take a few to our kill-shelter out of desperation, but I still believe safety — even if it leads to the tragic, disgusting euthanasia that is so common in our country — beats being hit by a car or shot by nasty humans. I’ve fed feral cats (practicing TNR) for over a decade as well, and have taken in at least 40 cats in that time.
Dogs and cats are a reason to live, in my opinion.
