Toto does that! I put a papertowel under her little food stand because she picks out certain things that she doesn't care for and cleanup is easier if she puts it on the towel.
Most of the time, before she eats, she tries to cover her bowl by covering it with the towel! We have tried and tried to figure out why she does it .... Patrick says she is saying her own little "Grace" over her food!
Do you think she's trying to hide it?
