It's been quite a while since we've seen a generous mama or unlikely BFFs – just when we were on a roll, the heartwarming tales seemed to dry up! Not so anymore as the latest comes in from Caney, KS, where a Golden Retriever stepped up, and stepped in, for a mama tiger who wasn't feeling so motherly towards her new cubs. Isabella will only take care of the babies for about a week (to get them past this critical state) at the Safari Zoological Park – the three little girls are growing quickly and will weigh in around 300 pounds when they are fully grown . . . much bigger than their foster mama.
