hello everybody i've got a 10-month old grey (a boy), and he's currently on a balanced diet of pellets, vegetables, and fruits (and an occasional nut). but he absolutely LOVES his formula feed at night before bed. i've been feeding him this formula since i got him (around 4-5 months old at the time). should i continue giving him this formula? his weight is normal - not over or underweight. thanks!
