I am going to be honest I am at a stand still both cats have there given names Stormy and Sahara. Stormy knows her name by call and will somewhat listen when her name is stated. On the other hand Sahara is confused. We decided to give her the nickname Tubbs or Tubby because she is a chunky girl and now she thinks that is her name. I am now unsure if I should change her name or just keep Tubbs as a nickname. Anyone have thoughts?
