HELP!

YIKES!  Please red below which I copied from DEFRA FOR DUMMIES.  I am nervous because I don't recall my cat getting any "boosters" after the rabies vaccination.  I got a form that shows she passed test and I thought I was too wait until 48-24 horus before flight to get anything else??!!
Does anyone have any advice?!!?  I am scared!


• Vaccination record
When your pet is vaccinated, make sure that the vet accurately records the
following details on its vaccination record.
its date of birth/age (AT LEAST 3 MOS. OLD)
 the microchip number, date of insertion and its location in the animal
the date of vaccination
the vaccine manufacturer, product name and batch number
the date by which the booster vaccination must be given (i.e. the Valid
until  date) 
 
Step 3: The blood test
After being vaccinated, your pet must have a blood test to make sure that the
vaccine has worked. Your vet will tell you the best time to do this and will take
a blood sample to be analysed at an EU-approved laboratory. Take your pet’s
vaccination record with you when the blood sample is taken. Ask your vet to
read the microchip and to give you a signed record of the date the sample
was taken that accurately shows your pet’s microchip number.
A satisfactory blood test result will show that the rabies antibody titre was
equal to or more than 0.5IU/ml. Make sure your vet gives you a certified copy
of the result, accurately showing the microchip number and the date the
sample was taken, and keep it safe.

Your pet requires only one satisfactory blood test and 6 calendar months wait
provided the subsequent rabies booster vaccinations are given by the
required date. 
 
Step 4: Booster vaccinations
After your pet has been rabies vaccinated and blood has been drawn it will need regular booster vaccinations. These must be given by the "Valid untiil date
in section IV on the PETS certificate and be recorded on
the vaccination record.
 
If the booster date is missed, your pet will have to be vaccinated and blood
tested again. The 6 month rule will apply from the date the new blood sample
is taken, provided the result is satisfactory
I have a record from the vet of the date the blood sample was taken,
showing the correct microchip number. 
IMPORTANT: THIS IS THE WEBSITE FOR THE ONE APPROVED FACILITY IN THE UNITED STATES & there is a PDF file that can be printed that has the request for antibody test (this must accompany the blood along with the credit card authorization form (charge is $40). http://www.vet.k-state.edu/depts/rabies/favntest.htm - they suggest a waiting period of  21 days between the vaccination and the blood draw for optimum antibody response results. Results can be expected in 4 weeks/I paid the vet and had them fill it out so the results can be sent to them. There will be a sticker in the middle of the form with an original signature, that it the certified one that will be sent to your vet.

Call DEFRA.  Really, they're the only people who can answer your question.  I'm going to guess here and say no, you won't need a booster, but call the experts!

Well I read the rest of the defra for dummies post and pretty much answered mu questions.  Haha sorry- I just immediately jumped to conclusions. 
GWAR.... I CANNOT WAIT UNTIL THIS IS ALL COMPLETE!!!
