Senoufou, your dafe husband doesn't need to build a special yokey - you can already buy cycle trailers for pets; I'm mumbling over the thought of getting one for my new puppy, who's going to be a big boy, so I can bring him to the sea and local parks for romps.

However, he might be wise to take a course in wildlife rehabilitation - there are skills involved, and knowledge. (For instance, you would never in a million years see me pick up a sick bird nowadays unless with rubber gloves and very much at arm's length, and probably not even then; there's a very nasty virus going around Europe that has already killed virtually all of Paris's blackbirds, and which is transmissible to humans.)

You may have seen a video that's going around the internet of an Irish vet (veterinarian for our American ex-co-Anglophones) jumping out of a taxi to run and rescue a young swan on the road at Donnybrook in Dublin. He wrapped it in his jacket, carried it to the river Dodder and let it loose, and it swam happily away.
