The Lady Iris (moved in some years ago without permission having been abandoned by her 2 previous families who moved away and left her) has 1 pouch in the morning and small bowl of dried food early evening...she doesn't ask for food as she has realised she won't get any.....she sometimes gets a chew stick..but rarely....her tum is also round but she doesn't leave the garden and doesn't catch birds etc. I would limit her meals to twice a day and not give in to the big eyes! Get her a health check at the vets.
