One of my Leopard babies squeaks and whistles when s/he sleeps. Sometimes it sounds like a cat meowing. I finally was able to discover which animal it is. There is nothing apparently wrong with her/him. S/he eats normally and when outside s/he runs around grazing and enjoying the sun just like all the others. But when s/he sleeps s/he makes all kinds of strange noises. Has anyone else had this happen or heard of it? I have seen several posts about them making some noise but this is an all the time thing now and it is starting to worry me.
