Got totally distracted by naming the tabby kittens but I came on here to ask about worming treatments. My vet is suggesting a spot of treatment every 3 months that costs £50 but I've always bought frontline which is much cheaper. My ragdoll had a serious tummy upset recently (he is ok now) so I'm worried it was caused by not using good enough wormer. Should I go with the vets £50 option or do others feel the cheaper frontline one is ok? Wondered what others use basically. I've had cats all my life and never remembered wormer being so expensive!
