I don't think they are gophers. But I did kill a few moles and seen some dead ones on the ground the neighbors cats had ahold of... played w but didn't eat.
Moles are nasty looking things. Voles I think just look more like a mouse, not really ugly like a mole. All I know is they were gone by the next morning-so much for being Queen of the Night!
I love using those ice cream containers for everything. I buy the square ones so they stack easily. they are semi-transparent so it's easy to see what is in them. I like to use them for mixing small batches of paint sometimes. Great for storing muffins, watermelon ect in the kitchen too! Craft supplies...
