I had my bunnies vacc'd two weeks ago and they were booked for the next lot tomorrow. I had to rearrange it for the end of the month as I just can't afford it right now. The receptionist said "are sure its okay to do that I'm sure you have to do it two weeks apart". She is very nice. I told her no that the 2 week rule was MINIMUM not Maximum. That is right isn't? I'm okay having them done at the end of the month? Just got me thinking...:?
