Its funny that this subject was started. My niece had to move and she could'nt take her cat so she gave it to my brother who has a mobile home on our farm, he told me he got the cat and turned it loose to help keep the field mice out of the house. The other day my DH says "hey, theres a black and white cat on the deck so I went out to meet the new member of our farm <and there are many>. Well it took off like a bolt of lightening headed for my brothers house all of a sudden this red squirrel is hopping across the field chasing it...was the funniest thing I have ever seen they both went running off into the trees behind my brothers house. I figure the squirrel had a nest with babies and went to protect them....have seen plenty of dogs and cats chasing squirrels but have never seen a squirrel chasing a cat.
