:Thanks for the message. Hopefully I'll have a chance to research this over christmas. Thought it was worth asking around though. As for squirrels, yeah they're persistent, but we make a big fuss of ours so we bring it on ourselves really. Your story about the dead baby squirrels was a bit upsetting. We've got a big momma squirrel on our block churning out two litters a year, so we have baby squirrels around most of the year. Anyway, cheers!
