Outdoor kitties can have shorter but more enriching lives. Here we make sure they are vetted as needed keeping up on wormings and vaccines, especially the rabies shot. Spaying and neutering is also good. Flea and tick preventative are applied as needed.Idk how to do anything about predators. She has a covered porch to eat/sleep on and so far has only gotten off of it to go to the bathroom.
She’ll free range like our chickens do, so survival during the day will pretty much be on her. I can shut the gate to our porch to keep her better protected, but if something really wanted on there I don’t know how I’d stop it.
I might get your kitty microchipped. Collars make me uneasy as they can get hung up on stuff.
Make sure to feed them well so they always come home. You could always lock them in for the night in a crate if you are worried. Some cats tolerate that and others don't.
We provide heated cat houses in the winter here. The cats will hang out in them most of the day. If it's warm enough they also like sitting in a sunny area. I like the K&H houses as they heat up when the cat sits on the pad.
