I was digging up some bamboo (never plant it, I hate it so much!) And uncovered a nest of very cute little things but I'm not sure if they're mice or rats... I'm also not sure if it makes a difference to be fair as I'm not killing them either way, but do I need to do anything to deter if rats? I know i shouldn't have picked them up but they were in like a little cavern and I was worried they would suffocate on the displaced soil. They're now in the hole with some leaves on... Help!
