I think animals have cycles; we didn't have any squirrels a couple years ago and I have seen no deer in the last couple years. We usually have 1-3 toads too but haven't seen any myself; probably the heat this year has changed things. We have rabbits but not in the usual places (I'm a veteran rabbit counter, can usually get 3-6 on the way into our development in the evenings) or numbers and a ground hog just appeared a couple days ago and yet seems gone again now. I'd never seen a ground hog on this property.
There's a field where there are normally herds of deer but haven't seen any the last year or two but my son and daughter-in-law's house, last time we went to babysit the grandkids, they're in a very routine suburb and there was herd of deer, 7 or 8 in their small backyard (an hour away). This is "my" toad from a couple years ago.
