Semi feral boy -that adopted me, he follows me around the yard whining. (maybe he's still complaining about being neutered?
Coyotes -at dusk
Mocking birds -all the time, these birds do not sleep.
Grackles -there was a huge flock of them in the yard the other day
Toads and Frogs -in warmer months
Cattle -making all sorts of horrible noises.
Neighbor's chihuahua, because they won't keep the thing on a leash and it has to run over into our yard and bark at me..... I've had to call Max down 3 times now. I really do not want to see what an angry, territorial 14lb cat can do to a tiny chihuahua.
Another neighbor's horse, poor thing is all alone out there and no one really spends time with it.
Neighbors themselves, building stuff, kids playing at the nearby school, etc.
And the usual insects - grasshoppers, katydids, cicadas, crickets and mosquitoes.
We also have a pair of skunks. I never hear them, of course.. but they do like to pop out and scare me, run towards me, ...come to "kitty kitty kitty".
And no, they're not rabid. They're just used to us.
