Hi.
 
I want to make sure I understand this correctly.

Two sprays per pound in a ferret but only one spray per pound on a cat?
That means that a 3-pound ferret gets six sprays and a 3-pound cat only
gets three sprays.  Unless I'm missing something fundamental, which is
always possible, it seems that this method would either overdose the
ferret and/or not provide enough protection for the cat.
