I do like cats, but I'm allergic to them, so allergic that I haven't visited my brother's house since he got his (freaking lovely) Maine Coon, I don't like taking antihistamine tablets, even less since I was diagnosed with epilepsy, since antihistamine medications don't play nice with my seizure medications.
I've read Siberian cats do not produce the enzyme responsible for allergies, if I was 100% sure about that I might consider getting one, but, still, I don't think I'd be very happy with cleaning all that fur and doing the cat's toilet, like my sister-in-law does with their cat.
But I don't like dogs, I don't like the fact that, no matter what, they will come near me - I know it's in their nature -, I like cats because they don't give a single, solitary, flying f*** about me, they don't bark at me, they don't come near me to sniff me or jump on me, if dogs are aggressive, they can be really dangerous, especially when they're mid-to-large size, I still remember when I was a kid a neighbor of ours was almost killed by his two Dobermanns, and dogs make a lot of noise, disturbing everyone in a condo or a neighborhood, especially when there are multiple dogs living in the same area, when one starts barking, all of them will bark.
One thing I dislike more than dogs, though, is most dog owners, I can't stand the fact that they think everyone is fine with having their dog around, everywhere they go, many times disobeying regulations regarding leashes and muzzle, if they have a separation anxiety problem, they should seek help instead of subjecting everybody else to their friend's presence no matter where they are, public transport, restaurants, cafés, parks, public gatherings, condos, stores, etc. Also, at least where I live, I've noticed, steadily, that the bigger the dog, the smaller their owner's brain; people should really be made to get a license before they can get a big, powerful dog, those dogs need training and need a responsible, level-headed person, not a douchebag who thinks having a Pitbull - or any big dog - is going to make him look cool.
