Maggie and Wellness cat food

Hi For almost 2 years now our cat Maggie has eaten only Wellness food. It has be challenging because she doesn't like fish or any of the other brands of food Tailblazers carries so she has had a rather limited menu. She is well and at a good weight.
My friend and cat sitter has introduced Maggie to Fancy Feast. Maggie likes Fancy Feast. Maggie wants Fancy Feast. If it's not Fancy Feast then it will be nothing. The Wellness can sit in her dish until it is petrified. She will not touch it.
Maggie should be a contestant on Survivor. She has what it takes. She can outwit and outlast.
I know it is not good for her to go without food all day long so I give in. She sucks back 2 and sometimes 3 of these little cans. What's in this stuff? Is it really bad for her?
She knows I don't want her to have it and it is affecting our friendship.
Help

Can you mix some of the Fancy Feast into the Wellness and slowly decrease the amount?

Just what I was gonna suggest LP :D

Put a small amount Wellness in the dish, mix some FF in it, then top it with a bit more FF to make it smell like only FF.

After a couple of days increase the Wellness, decrease the FF, and so on until you can get her off FF.

What flavour is the FF? Is it a flavour she's had before from Wellness?

Have you tried the Wellness Beef & Salmon?

Thanks! What a good idea. I am doing it right now. She may be smarter than me but she is not smarter than you two.
Maggie lives on Wellness Chicken, Turkey and Chicken and Beef. We have tried almost every canned food in Tailblazers. The Fancy Feast is Beef Liver.
Wellness Core has a new line with liver but I have not been able to get it even through a special order. It is on my list when we go to Calgary.
UPDATE: Even though I used more Wellness than Fancy Feast she ate most of it.:highfive:
Thanks again. Laurie

Great start :thumbs up
