The Pet Porte micro chip cat flap is astonishingly sophisticated! If
you want the very best for your cats check out http://www.microchipcatflaps.co.uk/index.htm

What's unique about this kind of cat flap is it lets your cat in and
keeps neighbours cats out without the need for a bulky collar. It
works by reading your cats existing microchip.

Best of all there is a night sensor that can keep your kitties safe
inside at night. This is an absolutely fantastic thing to have whilst
someone is looking after your cats while you are on holiday. Kitty can
always get back in but only go out to play in the daytime.

Cats feel much safer knowing that if they are being chased they can
always run inside and no other cats or other animals can follow them.
