The details
Apple seeds contain amygdalin, which can release cyanide, so the seeds and core must always go. The flesh is a good source of vitamins, but it is sugary, so keep it to a small slice as part of the day's fresh food.
How treats fit into a rat's diet
Most of what a rat eats each day should be a complete rat pellet or nugget, weighed out from the pack guidelines. Fresh fruit, vegetables and treats come out of that daily allowance, not on top of it: the RSPCA warns that extra sugar and fat lead to obesity and health problems, and rats gain weight easily. Remove any fresh food that hasn't been eaten within a few hours.
