I like cats, but good. I'd like to see a change in pet ownership attitudes in general, and as this is about cats I'll stick to discussing cats because whataboutery isn't helpful and this does need debating
It is undisputed that cats are responsible for the deaths of many wild creatures. They also have a tendency to defaecate in neighbours' gardens. Yes I know dogs also shit, etc etc, but this discussion is about cats. When allowed to roam they can dart in front of cars causing TRAs when drivers try and avoid them. So what can be done about it?
Firstly, owning a pet is a choice. No one has to have a pet, and if they do it doesn't have to be a cat
If they choose a cat it is possible to make a cat enclosure so they can't roam. This keeps the cats safe from traffic etc, while also keeping wildlife and neighbours happy
Only breed from cats with low prey drives to reduce the risk to wildlife, and only breed from cats who are content indoors. Personally, I'd like to see a major clampdown on animal breeding in general but that's a whole other debate! If this isn't viable, then make cats less of an appealing option for potential pet owners by saying they must be contained in their own home. For the most part they are chosen because they require minimal responsibility, so increase the responsibility and work that cat owners have and maybe we'll see fewer cats as a consequence.
