Dont know if its any use to anyone but i thought it was a good idea.
Avoid stressful trips to the Vet
You want peace of mind but your pet hates going to the vet? Don't worry, help is at hand - we can chip your pet in the comfort of your own home, and you'll pay less as well! Our mobile microchipping service is run by a trained implanter, who will call at a time convenient to you. The painless procedure, which takes less than a minute, will be explained to you beforehand, and your pet's details will be recorded on a national database (PetLog) administered by the Kennel Club. Help will be given with completing the necessary forms, if required. You stay with your pet the whole time so that he/she feels safe and secure.
Implanter trained by Pet-Detect
Although our prices are already lower than most vets, we also offer special discounts to breeders wishing to have litters of puppies or kittens chipped prior to sale. The majority of responsible breeders are now choosing to chip their animals - this not only protecs them should they get lost, but is also essential for identification purposes when (for example) health screening tests are carried out, and of course when animals are taken abroad and returned to the UK.
