I agree that's expensive for the flea treatment but I guess an injection of Program (that's what it's called in France) IS expensive, more than Frontline (I don't really know, I never did one). But that way you won't have to think about it once a month
. Next time you may put on some Frontline if you prefer.
6£ for 2 months for a cat for worms also seem expensive (that would be around 10€, where 6 or 8€ would be the price) but not so much.
The bill for neutering and microchipping seems right too (in France I think it would be more expensive : the chip alone costs 45-50€... and neutering 60€).
