2. On the occasion of a smaller animal where the child has less contact (i.e. goldfish, hamster, amoeba), the child does not have to know that an interpet has been used so long as the interpet looks similar to the original.
Oh mommy, Gravy is so cute! Daddy, hurry up and cover Biscuit, he's starting to smell!!
Okay honey, you take the interpet...I mean Gravy inside.
