We have found an ill adult male stray/semi feral cat and after it’s vet treatment we want to offer it a home. Unfortunately DH is very allergic to cats so were thinking of building an insulated ‘cat kennel’ in the garden for it with the idea of putting in a heated mat/ blanket in the winter. I was thinking of putting in a microchip cat flap on the ‘kennel’ as we have lots of other cats and foxes in our area. Has anyone done anything similar? Also recommendations for reasonably priced but effective microchip cat flaps
