Is most lumber at places like Home Depot pressure treated or not? Do they always mark it if it's pressure treated? How about the wood at Rocklers or Michael's craft store?
I got some hard maple from someone who did a home remodeling, and I think it was used indoors. Is this likely to be pressure treated or not?
I need to make some perches and toys for a pet bird and I wouldn't want it to die from eating pressure treated wood.
