Dogs don't generally do that either. They're more likely to steal food out of your kitchen. The hysteria about dogs is hyperbolic and out of proportion in the main.
However cat shit is highly toxic - worse tham dogs I'm led to believe - and can lead to blindness. Equally a hefty percentage of the population are allergic to cat hair, some very seriously.
I realise you don't like dogs, but whilst I largely like cats it's also nonsense to suggest that letting them roam loose doesn't lead to some issues
I have a dog! One of the additional reasons I hate dogs roaming is he's the most likely to come a cropper and be attacked by them (and he has

)
Dog poo is toxic and can also lead to blindness. Some people are allergic to dogs too. This argument of yours is really daft!
The thing is usually cats bury their poo and dogs don't. Walk down the street - have you *ever* seen a cat poo or wee on concrete/ tarmac.
The fact *some* cats don't cover their poo properly means they probably have been taken away from their mums too young how to learn to do it properly.
And 'hyperbole' I'm sorry. Dogs
do attack people and children, let's not pretend it doesn't happen - it does. Once in a blue moon a cat will go for someone, I'm sure you'll find an example because it's far rarer= 100 times more likely to get news exposure.
Some dogs are trained to attack! It's the reason some people keep them. Usually the ones who let them run around unsupervised too!
And I think you'll find in law - as much as you don't like this - cats are legally entitled to roam, whereas, in law dogs are not.
Just because in urban parts of the US cats are routinely seen as house pets (I'm sure the story is different in rural or suburban areas) isn't really a good enough reason to be vitriolic about the situation in the UK.
If you live in a US city, near lots of main roads and are about 17 storeys up in a flat, I daresay that's a good reason to keep your cat inside... however that isn't the reality for most people in the UK outside of London/ city centres.
