I get to foster a friend's cat for a while (probably like a few years), and I've been tragically lacking live-in cat friends for 4 years, so I'm out here googling how to catproof your house like someone who hasn't spent half their life living with cats, lol.
House must be perfect for Widget!
All the plants must be behind glass because she's never lived with houseplants, and I don't want her to get poisoned (And I've been enjoying my cat free years by getting into cat unsafe plants).
She loves her cat tree, so we must get a new cat tree! Cat tree area has been cleaned out, and litter box area is in progress.
I also need to get her a cozy crate so she can free nest in it. This super helped another friend's cat not hate the crate for vet time.
Fish tanks will all have lids because I don't know what aquarium plants are toxic to cats, and I love my fish.
Lizards are moving to cat free room so they don't get stressed out because I love my lizards.
Thankfully, since my friends live like down the street and have had her since she was a kitten, I know her health history, her vet, her favorite food, her feeding schedule, and all her adorable misbehaviors.
This is Very Easy mode of the Cat Distribution System.
