I have several crybaby cats, so, I wouldn't worry too much about that one.

However, what about increasing her play time? AND, please remember that this must be a gradual food decrease, as cats are susceptible to fatty liver disease, brought on by a significant reduction in weight. So, I am not so sure I would just decrease the food without some sort of consult/research on how much is an 'okay' amount.

Good luck, and keep us posted.
