Iffy has very recently started the habit of blood curdling yowls multiple times a night. She doesnt sleep in our room (usually wants out right away and has always seemed fine away from us by herself). Everytime I've checked on her I find her proudly surveying a 'kill' or carrying something in her mouth. I recently bought this small dog toy rabbit and she has fallen in love with it. She snuggles it,licks it, gnaws on its neck. And yea... howls like the dickens over it. Im glad other people have this happen, her yowls sound like shes getting HERSELF killed more than shes killing something.
