Smudge is about three months old now. He is eating Blue Buffalo, but I'm going to change him to Orijen when this bag of food is gone. Also, he is eating quite alot more than what is recommended. Should I cut back or let it go? Do you have a recommendation for a litterbox? I'm thinking about getting one of those that rolls to empty. I'm also open for any advice!! We also have a 2 y.o. Maltese. The two of them seem to get along pretty well.
