I agree to wait until the weather is a little better. Just do not leave them in the car. It can be cold outside but the sunshine in the car will cook them.
I can answer the animal question. It could be rabbit, deer, groundhogs but something eats some of my sedum down to the ground some they never touch. This year I sprayed mine early. We have had great warm temps for over a month and they had started to eat some of the sedum that was just coming up.
It took me awhile to realize that winter was not killing some of the small ground cover sedum it was something eating them.
