Suggestions of which cat food to feed super fat Quill now her babies are from her?

Hello
As from Monday Quill's babies will be taken off her which i have to say i am quite relieved about. She can start to shed some of those serious excess pounds she has gained! Could anyone please suggest which dry cat food / mixture i could feed her thats more appropriate to her requirements (please see the photo of her that i put on the topic about fat hogs, she honestly is huge) I can't wait to put her wheel back in and see her lose some weight as its really been worrying me.

I have put her babies up for sale so if anyone is interested please pm me.

Thanks all

I'd go with a small amount of her regular food so its a bit samey but a high percentage of an 8% cat food (I think its science plan chicken light that is 8%) and cut the treats out - hopefully she will get back on her wheel and start to drop slowly but steadily - if he doesnt start losing then perhaps look to reduce the amount of biccies shes eating a little bit and see how she goes - dont want a dramatic weight loss just something nice and steady each week til shes down to a more appropriate size for her
