Dr. Carsten Plishke is a veternarian from Germany who used LEGO to build a temporary “wheelchair” for a tortoise named Blade who suffers from a growth disorder. In an interview with the Daily Mail he talks about the limited options available for animals.
For people there are walkers, rollators or prostheses but for animals there are no companies that produce something like that. The size variation of animals means they can’t establish uniform products. So you have to come up with creative solutions; every animal needs its own treatment.
