the quarantine in england is 6 months, plus the deworming, rabies, etc (which is fine because they are indoor cats). but one of the cats is very susceptible to colds. She gets a cold every year so my vet said he didn't recomment it because even if I found the best kennel, if another animal came in with something minor, my cat would likely pick it up. Also, I am afraid of putting them in cages for 6 months. what if they are not the same at the end of 6 months?
