England makes cat microchipping compulsory, extending the existing dog regime to cats. Under the new plans, all keepers must ensure their pet is microchipped before they reach the age of 20 weeks and their contact details stored and kept up to date in a pet microchipping database. Enforcement mirrors the dog rules: Owners found not to have microchipped their cat will have 21 days to have one implanted, or may face a fine of up to £500.
The policy followed public consultation: The new microchipping rules follow a Government call for evidence and consultation on the issue in which 99% of respondents expressed support for the measure.
Government-cited population figures (Dir1 — government pet-ownership statistics) show the scale: There are over 10.8 million pet cats in the UK, with as many as 2.8 million unchipped, meaning that it would be very difficult to reunite them with their owner if they get lost or stolen. Reunification evidence: Eight out of 10 stray cats coming into Cats Protection’s centres are not microchipped.
This is the government pet-identification/registration regime (Dir1), extending gb_pet_microchip_registration from dogs to cats.
