I recently changed my cats diet after realising that hills science plan dry food was making my cat put weight on and not loose it? I have tried her on various dry food diets and all she has done is put weight on and not loose it. She has also been tried on whiskers wet food but she woke up one day and turned her nose up and refused to eat any of the various favours I had for her. I put her on sheba and she loves it. Is sheba good for cats? She is also more affectionate and active on sheba. Thanks for any advice.
