What do you mean by pet sensitive? Living & working in a rural area I've known PIR floodlights to be triggered by foxes and badgers etc. (much to neighbours' annoyance).
Not that I'm aware of, maybe if the PIR is set to low sensitivity or angled/sited high up you may avoid this but then it won't pick up short burglars! Perhaps someone else knows better?
I have seen or heard of pet sensitive pir lights somewhere but it sort of defeats the object lol. Just aim the pir higher so it doesn't pick up the pets lol. Good luck tho
