Default p.180 rabbit and fox in circular cage

Are there any hints or solutions to the page 180 problem?
Fox chasing rabbit inside circular cage, both have equal speed. Will fox always catch the rabbit?

Thanks,
Philip

Default the solution

I found the answer (thanks to N.F.) but the solution gives me a headache. I would strongly encourage 99% of the readers of the book to not spend time on this problem.

Answer seems to be: rabbit can keep escaping forever. The original problem is worded as lion chasing a man.
For a very terse proof see Littlewood's "A Mathematicians Miscellany".

Best regards,
Philip
