I have 3 baby fox squirrels that I would guess are going on 4 weeks old. I’ve had them for a few days now and have been using EPR. I really dislike the smell of it. I had forgotten how bad it is. Their urine, poop, and they themselves smell like it. They are doing well on EPR and I had no intent of changing but if FV smells better I may have to make the change.
