I'm going over my monthly expenses budget because Felix needs another dental and I currently spend ~$68.42 a month for both cat litter and food. I've already cut cost in the food department and I'm wondering now if there are clever ways to make that 40lb bag of clumping litter stretch for 2 months between 3 cats. Or if there is another type of litter I could try that would last longer. I'm in Canada by the way in case anyone has any suggestions.
