^ Yes, that is why there are so many fatalities from cat attacks. Though it isn't so much a toxin as the bacteria present in the cat's saliva, which happens to be of a virulence that can quickly cause a massive systemic infection (blood poisoning) in small animals. The fact that they create puncture wounds does not help, either, as these close over quickly and trap infection inside. We like to say in the wildlife rehabilitation community that for every animal your cat bring's home, he's killed about 5 others. Cats have a nasty habit of just injuring and "playing" with wildlife, instead of killing it. That is because they act on instinct to stalk and attack, but so long as they are a well fed house cat, often do not kill or eat the animal. So, while your cat may sometimes kill and consume an animal, chances are it bit, clawed, battered, and played with several others that will then go off to die of shock or bacterial infection from the bites. Outdoor pet cats are not natural predators (meaning they do not hunt/kill like wild predators, and do not have numbers and abilities controlled by disease and injury, etc.) and thus pose a very serious threat to wildlife.
