My leopards are gonna spend their first year outdoors.
I live in So Cal so the high in the winters is about 75 and the low may go to 50-55.
I have a heated house for them that I have to place them in every night (probably because it is not cold enough now for them to search for heat). They know how to get out of it but never attempt to enter it at night.
What is the best way for them to figure out the way in?
