Allow your cat to enter and leave your house without a cat flap. This lets your pet move around freely and encourages exercise. It also reduces the risk of overweight and eases boredom. Taskers can put cat flaps in wooden or uPVC doors Some can also work with wall installations. https://www.repairmywindowsanddoors.co.uk/croydon-cat-flap-installer-near-me/
