It is interesting to note the divide on this one between hunters and farmers / ranchers.
Feral cats don't bother me at all. They keep the rodents and birds out of my horses' feed.
For that matter, I like rat snakes.
Another thought - beware the culling out for predation due to boredom's sake rhetoric. Most of the hunters I know don't actually need to hunt. That's not to say they waste meat, but they hunt because they want to, not because they will starve if they don't hunt.
