We have had many feral cats here i Wild Wonderful Wyoming. They lived in an outbuilding (since torn down) And the coyotes just loved the place. I thinned the yotes a bit and my wife used the havaheart trap to catch the kitties. Took 'em to the vet and had 'em spayed/neutered and rabies worm shots etc.. We have two cats now..one was an uncatchable feral that we fed. he came up after fighting with a coon. Saw the fight. It was a draw I think. Skinny little 6 pound cat agains a very large coon.. Wife fixed him up...took him to the vet...and eventually he was neutered cause he didn't leave. He now weighs 16 lbs and is still a great critter getter when outside. The other one is a much smaller cat that lives inside and kills anything it sees in the house...from bugs to mice. I went outside the other evening and the cat was out there. Yowling at me to pick him up or something. A very large coyote came running to exploit the cat and ran right into me. He stopped at about 3 ft,,snarled,,,cat was already up a tree. The yote didn't make it past the ol Wilson Combat. BTW..this cat will not allow any other cats on the place. Really unusual as he was the only uncatchable one of 14 wild ones. Wife used left over chicken salad as bait in the trap. He still won't eat it. Raw chicken and raw beef...oh yeah. He is now approx 12 years old or so.
