First off why is a 3-4' Boa eating medium mice? Should be eating almost medium Rats. As far as snakes needing excersize? If you give them something to climb on they do not need excersize. They get weekly(at least i hope they do) excersize constricting prey, and the occasion excusion outside.
Unless you have an exceptionally picky BP , a "Hot" or something else really tough feeder. There is No need to feed live.
The person can make all the excuses in the world, but it basically comes down to , the person gets a cheap thrill watching a snake Kill its prey.
Yes there are some exceptions. Boas are not one of them. Anyone tells me they can not get a Boa to eat f/t give the snake to me for a month, it will when Im done with it.
