Me again 
I'm just wondering the above. Our cat is a teeny little thing, only 3.2kg and slim built with it too. She needed to put on weight so we just fed her what she wanted.
She's now eating 2 sachets of Felix a day, and is also getting through a bowl of dried food too - we leave it out as we are sometimes out all day. It's decent quality dried too. She does ask for food.
Is this too much, compared to other cats her size?
