My cat seems to be eating more and I don't understand why as she is on go cat and whiskers dry food and until a week ago she had 40g per day split into two meals a day and this seemed to satify her, but over the last 5 days she has been wanting more as when she has finished her breakfast around 8am she stands at the kitchen door meowing to get in and then when she is let in definatly stands at her food cupboard until I feed her more. When she has her evening meal around 4pm (20g) again when she has finished this she wants more and then during the early hours of the morning she wakes up at 4:50am to 5:30am meowing wanting food as well. She has been on various other foods but she seems to only like go cat and whiskers and has been on this since 10 months old. I have tried her on wet food as well but she only likes sheba and tended to scoff two 100g trays of this daily when I was feeding her this, all other wet food I tried her on she turned her nose up to and wouldn't eat it. My question is, is she wanting more because she is growing up as she is 2 years and 6 months old as it just seems weird her appetite has increased suddenly? She is an indoor cat as well but has alot of burstful energy where she plays alot and weighs 4kg but a month ago was 3.8kg.
