My Vet does not think that is what she was doing. He thinks that maybe she was just smelling it. He has never heard of a cat doing this, only dogs. I did not see her eat it. I just saw her head down in the litter box, and it looked that way to me. I have not seen her do it since, and I am keeping a good eye on her !! I will keep you posted if I see her do it again.
