When furry friends are scared it is amazing the strength they produce. My husband found out one time trying to break up a cat fight. Our cat and the neighbors cat. We were young and foolish and let the neighbor bring their cat over to see if our furry friends could be neighborly. Well they wanted no part of one another to say the least. We got them seperated to say the least my husband had bruises on his legs from them grabbing a hold of him. It was a good thing he was wearing jeans. We never did that again. Pets stay at their house & ours stay at ours.
