Hmm, I'm used to avoiding cedar for the chickens and guinea pigs.. I wonder if the cat cares about cedar..I use cedar chips on my outside cats for bedding fleas hate the smell of cedar and lavender and other strong cents like that
Guess I'm hoping to kill them off of the cats more than just repel them.. however, any amount of making them feel less welcome will definitely be considered as PART of the solution, thanks for the suggestion!

This invites the question about Neem oil.. is that also just a repellent. And wonder which one is less annoying to the cats? I did have a cedar stuffed dog bed in the past and my dogs didn't mind it AT all.. that would mean the cedar oils were NOT in contact with fur/skin but still heavily smelling wonderful (to me).

However I recognize the OP's question is not focused on parasite control even though it was about feral cats, and will try and be sure not to hijack the thread.. though it *may* be helpful to Waves as well in the future.
