Your right of course fizz it could work if it was sold to someone who made concrete animals only.
You will probably find though that those that make concrete animals also make concrete statues and concrete bird baths and concrete fountains and probably refer to their occupation or businesses with reference to "concrete sculptures" or "concrete sculpting" rather than specifically concrete animals.
The name might suit with se listing for people specifically searching for concrete animals but then wouldn't concrete-animals.com be better for that?
Anyway, to get around the cost of postage maybe machine should consider concreteinsects.com
