The magnetic Staywell cat flap has been working brilliantly! Our old regular catflap was broken by a neighbour's tom, who likes to make unwelcome visits and then hurls himself at the flap to get out. After finding the broken flap and the stink of cat spray yet again, we decided enough was enough. I was wary to buy a magnetic type as the reviews are mixed, but my cat Bathsheba has really taken to it! She is used to wearing a collar and using a cat flap so this helped, but she got the hang of the magnet fairly quickly, with lost of biscuits to encourage her. CatFlap sent the new flap extremely quickly too which was very helpful. Thank you!
