Both Louie (on the left) and dieting Beegie (on the right) enjoy chasing the light from a laser pointer. I make sure not to aim it at their eyes. I really think the little bit of activity this has given them has helped Beegie to start taking off the ounces she's lost since I put her on Purina Overweight Management (prescription from vet). The two are fed separately and I have been pretty good about remembering to put Louie's food away. If I was perfect, Beegie would have lost more weight!
