I'd say that 10' is plenty close for those critters.
When I was 13-14 years old I worked for a guy with a bait shop. He wanted a coon for a pet. I went fishing early one morning at the local boat harbor and spotted one in a 50 gal. trash can. I got a piece of plywood and some concret blocks and went and got my boss. You should have seen the blood-hair-fur fly! He finally got him in a gunny sack.
He took him to the bait shop and put him in a cage. After a while the coon got out, and ate just about everything in the shop.

PS-I picked worms for him also. Got $5 for a gallon of them in a ice cream container.
