Yesterday my (indoor only) cat left a small rat in my bedroom. I have been hearing strange noises in my kitchen at night. When I find the hole the rats are coming in through, what should I fill the hole with. I want something that rats can not, or will not, chew through and that is easy to use. Thank you in advance for all replies.
-- Whenever I hear or think of the song "Great green gobs of greasy grimey gopher guts" I imagine my cat saying; "That sounds REALLY, REALLY good. I'll have some of that!"
