When I was in grad school, I had a married friend lived about 30 miles south of Atlanta on a small farm. His wife worked at Six Flags, and she brought home some feces from the tigers and spread it around their garden.

No critter would DARE to go near it.

Possibly more difficult to come by than carcasses...

I knew someone who kept big cats. If you want to see something funny, check out the expression on a person's face when the horse they're mounted on gets a whiff of lion urine........

Yeah, but we went through this whole thing before, and I accidentally started a huge controversy when I told what I thought was just a funny story about trying to doing the right thing and having it come back and bit me in the ass (There was a nuisance skunk that used to hang out in my back yard and under the crawl space in my house, so one night when I saw him in the yard, I shot him. Then when the police came around saying they had reports of shots fired, and did I know anything about that, I could have just said, "Geel, officer, I heard a noise, I'm not sure if it was a gun or not, I just don't know", but instead I said, "Yes, I shot a skunk that keeps spraying my dog in the backyard," and then he wrote me a 200 dollar ticket for discharging a firearm in a residential area.)

Modern air rifles are very powerful, and much quieter than a firearm. And at least at the federal level they're not defined as a firearm, and not subject to restrictions placed on firearms. That does vary from state to state.

Well this is Texas hahahahaha

Surprisingly TX regulates air rifles as firearms in certain circumstances, but there's no law against firing one on your own property as long as you don't damage someone else's property.

Get an air pistol.

I have the Benjamin trail something or other. 540 FPS and it shoots straight.

I’m good to 10yard and that’s shooting a lizard’s head about the size of a nickel.
