I need to capture a half-feral cat with a serious medical problem. I

string once the cat enters. This won't work unless the door closes
and at the same time a knot ties it shut. The knot needn't hold long,
10 seconds against a large strong cat should do the job. Question is,
what knot should I use?

You need to arrange that as the door closes something else locks it - a
piece of bent garden wire or length of metal would be my choice.

I think something is missed there. For the cat to enter, people need to stay a fair distance away. That means the string would have to hold against a strong and very frightened semiferal cat, despite being pulled from a long way away. I don't see that working.

You will only get one chance since the cat won't be stupid enough to
enter the cage a second time if you fail.

of course.
