I think by sheer number, ornamental plants outnumbers species brought in for hunting/food.
Cats and honeybees should be on the list if we are being technical. If we killed all the honey bees, many of the invasive plants they pollinate would disappear as well. As for the cats? You first... No man in Ulthar may harm a cat.
Its already a thing. I hunted feral cats in central Queensland along with rabbits and foxes.
Feral cats are a huge menace, at least in Australia. They go through endangered native wildlife like a hot knife through butter. It can be confronting to people because cats are pets, but they're carnivorous little killing machines, and shooting a breeding pair might save thousands of birds and small mammals.
I've heard bobcat and mountain lion taste amazing, any info on domestic? I have a deal with my pets, they eat rats, and I don't eat them. They have been doing there part so... Also, they keep my feet warm.
Can't say I've eaten them, but I have turned in some cat at a pet-meat butcher, they said that not all animals like to eat cat meat.
Apart from humans.
Unfortunately our records don’t go back far enough to say for sure.
