Cage size, vaccines

Question
Hello

Is a cage thast 3x2x2 feet largwe enough for two ferrets?
I got a ferret from a petstore and on his health record it says he has had two distemper vaccines but they are feline distemper I have heard they need canine distemper because they are immuned to feline distemper is this true? If it is then are they vaccines that he was given no good? At what age is the rabies vaccine given?

Answer
Yes this should be large enough for two.  I would not put more than two in it though.  
It all depends on your vet as to what kind of shots they give.  So I would speak to the vet you are going to use.  All are different.
At what age the rabies is given depends on your vet as well.  Again, all are different and do things differently in different states.  So what my vet does might not be what yours would do.
