I'm 110% positive that the same goes for humans.
Just imagine how little deaths from being run over we would have if no human, ever, crossed a street.
This point has always baffled me. It strongly implies that since there's a risk of death to humans, it's pointless to try to minimise that risk for our pets. Pets don't
have to wander unattended. It's always the owner's choice whether or not to take the risk and I would argue that the risk isn't worth it.
I could easily turn that around and complain about the amount of hurt dogs cause - including those dogs that never roam free. A reasonably sized dog can kill a human, while cats run away like crazy if you say "BOE!"
I sadly know MANY examples of humans being killed by dogs. I have yet to hear about any human being killed by a cat.
Yes, most dogs pose a greater danger to humans than cats do. No argument here. That's one of the reasons I get infuriated by the number of dog walkers who let their dogs run rampant in the local park. It's also one reason why I support laws that require dogs to be kept on a lead in public.
Bringing up the size of the dog does raise an interesting point though since there are dog breeds that pose no more danger to humans than cats do. I take it you'd be fine with those in your garden?
Also, your dog really doesn't require cats to get parasites and alike.
Cats roaming free increases the odds of it happening though, doesn't it? It's also pretty disgusting to have to clean up.
Would you be okay with dogs pooing in your garden?
If you don't like cats in your garden, spray them with the hose. Do that 2 or 3 times and I assure you, it won't be coming back. It would have to be some seriously stubborn, almost abnormal, cat for it not to be deterred by such.
Again, apply this logic to literally any other pet. If you aren't happy with it in your garden, just spray it.
Here's an idea: if you don't live in an area where having (free) cats isn't an issue, then perhaps don't get cats in the first place.
I always die a little inside when I see folks living in an apartment on the 15th floor in the middle of a metropolitan, with cats.
What areas are you thinking of where free-roaming cats aren't an issue?
Frankly, my stance is that if you think it's cruel to keep cats indoors then fair enough. Don't have cats.
I think my core point in all of this still stands though. Even if you feel the freedom offered by letting your cats roam free outweighs the danger, other people are going to have to deal with any damage, mess and disease your pet causes. That just isn't fair on other people and cats seem to be the only pet that even makes this a debate.
