I saw this on tv the other night its terrible, I think she was a hoarder, but obviously it all became too much for her, she probably started off with less than half of that than they continued to breed, the fact that there were puppies there 6 found dead, and another litter just 2 days old laying in all that rubbish trying to feed of their emaciated mother, it is all just very sad. lets hope most of them can be saved and found good homes.
