i remember reading about wet food that was contaminated with the bird flu so its not a 100% efective trick

Straight edge outdoor cats

Unless I get it and give it to them.

Or my dog tracks something in on her paws.

Or my dog catches it and gives it to them.

Or my parents cats who they fucking refuse to try and keep inside will catch it and expose my cats even though they’re kept separate.

Or a sick bird smacks into the window
