Dear Edwina:

You are still loved very much. You have to realize that your furless ones spent time with you when they adopted you, to make sure you were comfortable and liked your new home.
Well now they have to make sure that the new boy cat is comfortable, so they have to spend a little more attention to him.
Also, you can never have enough male attention. So buckle up sweetheart and give the new guy a chance. Who knows, he just might land up being your best friend.

Sincerely
Tabby
