Cat wisdom please..help me change her food.

[MrsKingfisher]

2 cats, one eats as if he lives at the Ritz high meat content no grain etc..fatty will only eat Whiskas which stinks and doesn't fill her up. I have tried everything to get her off it what else can I do?

She will eat good quality biscuits so perhaps I should offer that for a few days then a new wet meat? Please help!

Mix small amounts of the new one in with the old and see if that works

Tried that, she will eat around the mixed bit or if it's too mixed up she'll refuse the whole lot!

Cats are wee shite bags really (i have 2)
I leave good quality grain free biscuits out all the time and give a variety of wet food - some good and some not so good

We have microchip feeders so they can't eat each other's however if I leave his lid open little fatty will eat his food! If I put the same food in hers she looks at me as if I'm trying to poison her.

I'm sure there is some cat psychology there somewhere...

Try Nieren from zooplus, my cat goes crazy for it and is a former felix/whiskas obsessive.
Also a big plus is that it neutralises their poo - no smell.
You can get small starter packs to see if they like it.
