Repurposing Pine Pellets

Q: I have recently switched my cats from clumping clay litter to pine pellets. How can I repurpose the pellets somehow in my yard?

A: I don’t see a reason not to use the “enriched”pine pellets as mulch underneath your shrubs. You could also mix the material into the soil as you make new flower beds. I wouldn’t use the pellets in a vegetable garden but otherwise they seem safe to me.
