Ive been to look. There are three separate cages of kittens, two pens in the front of the shop, the kittens look around 12 weeksish. One cage at the back amongest the rabbits, parrots, budgies, rats etc etc, the kittens look younger, and are marked as British shorthair crosses, three of the kittens were just laying down, the other three were playing, one of the three laying was laying in a dirty litter tray. I couldn't see if any of the sleeping kittens were poorly or had bad eyes. The kittens at the front had clean litter and fresh food and water. Whilst I was looking another lady came in and looked and was saying 'poor little things shouldn't be in here'. I go into Margate quite often so will keep an eye.
Lucypersian, the RSPCA inspector should call you with an update if you requested one, but........ Ive reported a particularly bad case in the past where the cat was badly injured and was left with skin hanging off his face, The new welfare law wasn't in practice then so the Inspectors hands were rather tied, but all he did was give them advice on taking the cat to the vets and neutering. I have history with these particular people and cruelty case in the past, they are known to the RSPCA on a number of complaints surrounded Cats, dogs and rabbits. Infact they had dead rabbits in their garden left in hutches for weeks, according to a neighbour who kindly kept me up to date. Hopefully know the inspector can take a bit more action. On hindsight I wish Id of taken the cat myself for treatment., but went through the proper channels because I hoped that this time this people may get some sort of conviction and their animals taken away. They use their animals as breeding machines to make money.
The local Animal Rights group here are active and do campaign successfully against pets being sold in shops, last year a Ramsgate petstore was stopped before it even started.
edited to add - there were more kittens marked as british shorthair crosses today then, looking back at the original post!
