The Animal Trader Licence mandates that all cats and dogs undergo a veterinary examination no more than 30 days prior to being offered for sale. Do not purchase if you are suspicious of the petโs health condition, or if the seller refuses to provide relevant medical documents. The Agriculture, Fisheries and Conservation Department also recommends that owners take their newly purchased pets for a veterinary examination within a few days to ensure their health, even if they were purchased from a licensed vendor.
