wow...it's been about 35-40 years, but that warning brought back memories...we lost out family cat that way when his flea collar got caught on the garage door. so tragic and unforeseen (at that time), and now, with knowledge, preventable. i'm sorry for your friend's cat, and of course for the poor cat itself. we had a cat named blackie, too, in those days. :( though our unfortunate one was named putter. daoine o', aka the ferret queen pixie, burleigh, and shay and all those waiting over the bridge...
