hire a greyhound for a few days
My dad was once using it in the garden and he discovered a frog with almost the entirety of its skin blasted off. On that evidence alone I'd say it'd work like magic on cats.
Mine cried at the door to get out one day, when I let him out he just sat outside the patio door looking in at me. Fucking weirdoCats are very arrogant just wandering about all day and night shitting and staring at people ...... One sits on top of my car staring in my front window and when I'm out it lies on my drive so when I pull up just lies there like a twat ........ I hate the thing but it knows its too quick for me so nothing I can do
