our old cat (passed away from cancer aged 18 &1/2, about 18 months ago) used to chase dogs, Alsastians, Boxers, Rotties, he weren't fussy.... if it barked it was fair game....
hilarious , seeing the dogs running for their lives once they'd figured out that it wasn't a joke..... always reaffirmed how stupid dogs really are.... to be fair, he was a fair size for a moggy.... the neighbours asked if he came with a saddle when we moved in..... 6 weeks later, he went in thru their open kitchen window, and half inched their Roast chicken , just before they sat down for sunday dinner..... i was terribly polite, but had difficulty keeping a straight face , or being terribly cross with him, as they timidly knocked on our door to see if he'd brought it home with him.....
I took pity and handed them our leg of Lamb , and then spent the afternoon giggling insanely.... The Mrs was quite cross about having to settle for sausages for sunday dinner though....
they had 2 rotties, both were terrified of him within days of him being allowed out of the house to claim his new territory....
