Litter?

My floor is plywood, painted with exterior house paint. Stays fairly clean except just under the perches. Saw some had wood trim holding in pellets, litter, etc...

What is best to use on the floor under the perches for easy clean up? I put a pan of wood shavings, duh, it was so light that when the wings flap, the shavings go everywhere! Concept worked well tho, droppings do go in the pan. So, back to the think tank...

I read some use kitty litter. Is this standard, generic cat litter? Don't the birds peck at the litter? Isn't that harmful if ingested?

What are the pellets? I asked one member and got no reply.

Thanks in advance!
