My vet called today and said it was time for me to schedule an appointment for Tails' distemper booster. The only problem is, I took him in the first time for his booster since he had the original shot at the anti-cruelty society where he was before. I have never heeard of a cat needing two boosters for distemper, Memphis only needed the one. Is it different because Tails is only 3 months old? Or has my vet gone bonkers?
