Yep, that's why you will often find holy wars between American and British cat owners over letting cats roam.
By and large, in Europe (and especially Britain), cats have no real impact on anything.
Even the Royal Society for the Protection of Birds reckon cat predation does fuck all to bird populations (in the UK/British Isles) and mostly just culls birds that weren't gonna make it to breeding anyway.
The other thing is that unlike the US, most of Europe has no real "predator" like coyotes that pose a threat to cats roaming. The main threats to roaming cats are automobiles, rat poison, and the neighborhood cat hating sociopath.
