Good question, it doesn't work differently for cats. It's just that if antibodies are high you know for sure they don't need a booster. But if they're low it could mean they need a booster or it could mean they don't - I suppose in that case most vets and cat owners would choose to give a booster just in case.

To this day, I believe that getting the 4 vaccines all at one time was his undoing. I felt it was just TOO much for a wee kitty to cope with. This concept had just come onto the market and was still in its infancy. My understanding - from my new brilliant vet - is that the vaccines are better now than they were 10 years ago.

Merson had his full set - initial jab & follow up 3 weeks later. It was just after the last one that he fell ill. He never got another vaccine jab until April of this year and that was only because quite a few new cats have come into our area but they don't all look well cared for. That also answers your question about him going out. Yes he did & does. Always has and he loves it.

However - Havoc posted a VERY interesting piece from the FAB recently about boosters being given before 12 month due date would mean only one further booster required to give lifelong immunity. An option that I am most DEFINITLEY considering for my three going forward. I have always thought that we over vaccinate and it is a relief to know that many other think so too.

It is difficult to know what is right & what is wrong with vaccines. My old Slugger never had a vaccine in his life, lived to a good old 17 years and only had a health problem twice - both times with his thyroid.
