Cat Piss.

OK, you poison rats with **** you buy at Home Depot, no guilt? Then the cats or dogs kill the rats ingesting the same poison. Same result, but no guilt? 5 feral kittens under my house.. I catch them all and take them to the pound. They are dead before I get home, straight from the shelters mouth: "all feral kittens are euthanized" Whats the difference? End results are the same. I admit its not the best way to keep cats away. Just get a dog...to chase and possibly kill ANY cat, again...with no guilt. Prison time does not exist in Cali anymore......
There are pet friendly vermin poisons on the market. Kills only the rats. I have no guilt whatsoever about killing what even The Bible calls vermin. The difference is, the feral kittens and those killed in shelters are no one's pets. Although still sad, that's the truth.
