dust masks for feral friends, and notes on copyright

how about masks, disease, for ferals. birds included, available at parks and nature centers? 

copyright: the concept itself is not anyone.s property.  detailed  intellectual theft of, say a dust mask designed by someone other than you is a copyright violation.

In emergencies and for the benefit of the people, you can waive copyright costs.

if not it.s intellectual theft and unpaid labor, or, slavery.
