Toxoplasmosis is kind of a tricky subject, but cultural prevalence of it seems to have more to do with other things than cats.
Also: Getting asthma? Are you serious? Yeah, some people are allergic to cat hair/dander, but that applies to dogs and a hell of a lot of other things too.
And dogs shed. I hate to break it to you, but they do, and generally-speaking cats groom their own fur fairly well unless they're obese trainwrecks or otherwise really messed up.
I'm not even going to touch the "dying" part because it's so out of left field.
I think you're just trying to hate cats at this point.
I mean, I don't give a damn if you dislike cats. That's fine. But you're giving completely bogus arguments about it just to justify your own personal tastes, not to mention being fairly caustic about it here.
I'm caustic as a matter of personal pride, but cats are filthy animals, their skin, hair, feces and mucus are all laden with TONS of horrible stuff that is contagious to humans.
I don't know if cats "cause asthma, omg!" but the rate of asthmatic patients living with cats is higher then asthmatic patients living without them. There is a direct coorelation, but I do not claim to know the cause of it.
If you don't want to get sick and get brain parasites, don't get a cat. Yes, they are adorable. No, I don't want to go insane if i happen to rub my eye after petting them.
Whats wrong with getting a dog? The worst you can get is intestinal parasites if you trip on LSD and eat your dog's poop in the name of science. Otherwise they actually make you healthier (according to certain studies conducted with elderly people with dogs compared to elderly people without dogs), but cats? Man... I'd rather not have them anywhere near me, just because they will hop off my lap with 0.5 pounds of shed fur and 0.035 pounds of parasites.
No thanks homeboybrodude, I'll stick to dogs, and more dogs, before letting a cat live near me.
