Best Diet Food

What would you recommend the best food for over weight cats?
We currently feed her Hills Science Plan but have recently been told this may not be the best food for her, she is an indoor cat also so she doesn't get as much exercises as some but is still an active cat.
We are finding she isn't loosing the weight and we are feeding her the right amount for her age etc?

Any advice would be great, thanks

That is going to depend on the kitty. Hopefully, sharky, our resident food guru will be along with questions & advice!

I see your in the UK...

I am not terribley familiar with most UK brands ...

How old is she>???

Do you feed only buscuits or tinned also??

what wt should she be??

Thank you, She is only on dry food and is three years old, im not sure how much she should be but i'm taking her to the vets on friday so i will get her weighed again and make sure i Write it down

I would recommend adding tinned and possibley trying if $$ and kitty allow just tinned food ..

Yes current and ideal wts plus how much in what length of time the vets wants kitty to loose
