Context: Today , I trimmed Oona 's claws with only 50 % of the fuss that used to be there . I found that when she sits in the palm of one hand , one rear paw tends to hang off the hand . So I managed to trim the claws on it while she sat there unfazed . After a brief adjustment , I managed to get the other one to hang over instead , and trimmed its claws . The only fuss occurred when I dealt with her front paws . They never hang out , so I had to do the old " flip her on her back and keep a firm but not injury inducing grip on the paw in question while she looks up confusedly at me and eventually thrashes like a maniac " .

Question: What may be the reason for them fitting in a palm of a hand ?
