Strictly speaking I expect it is however I bet masses of cat owners stop bothering after the first couple of years with rare problems. Not surprising as it's just cost me over £70 for 1 cat.
It is, I even wondered if she made a mistake as I paid £37 for the first one and then asked for another £35 this week for the follow up (standard 8 week and 12 week). the receptionist assured me they charge for each injection.
Would you risk it?
Hopefully not.
If you go to a 'Vets for Pets' they do a one off payment 'Vacs for Life' programme which covers yearly vaccinations for the rest of the animal's life for £99. Saves money in the long run :-)
My two kitties are both on 'vaccines for life', which means the yearly check-up and vaccines are pre-paid, and as now they've now done over 6 years on it, I think we're 'in credit'.
As Robbie came from a farm campsite, the vet said he was more vulnerable to kitty HIV, so I think it's worth it for peace of mind.
Just an interesting note about Vet4Pets and their Vaccine for Life. They do their vaccines at a massive loss leader - then they are trained to try and "sell" or "detect" lots of other problems/treatment that need are then added on at a massive mark up. Their model is to attract as many people as possible with vaccines and then make large amounts of money of the "extras". Buyer beware.
My cats' vaccine for life is not through 'vets for pets', but through a local independent vets. It was slightly more expensive than them, but has more than paid itself back.
