If you got your cat as a kitten, six months is the perfect age to train her to use a cat flap. At this stage, cats should be vaccinated, and mature enough to go outside on their own. But you can follow these tips with a cat of any age; just be prepared to be a bit more patient with older cats who may not have used a cat flap before. These five steps should soon help your pet overcome any initial feline nerves and get them using the cat flap with confidence
1. Introduce the cat flap
Initially, keep the cat flap locked, and begin by simply feeding and playing with your cat nearby. Anything you can do to create positive associations with the cat flap, such as leaving food treats in front of it, is helpful.
2. Open the cat flap
Prop the cat flap open with heavy-duty tape to make an inviting opening for your cat to move through. Timid cats, especially, will appreciate being able to look out and see what awaits them on the other side.
3. Use rewards
With a person on either side of the open cat flap, use high-value food treats (perhaps some chicken or fish, or other favorite snack) to entice your cat in or out. Alternatively, you could use a toy to tempt her through the opening.
4. Take it slowly
Repeat the above a few times a day, for a week or so. Some cats will quickly become confident moving through the cat flap, while others may take longer to get used to the idea. Never force your cat through the opening, especially if you sense resistance from her. As with all training , practice makes perfect. This is really about creating natural confidence in your cat.
5. Drop the cat flap door
As your cat becomes more familiar with the opening, you can then drop the flap, so that she has to push lightly to open it. Once she’s comfortable doing this, she should be able to come and go as she pleases whenever you leave the cat flap unlocked.

No - The glass in the door should already be toughened and you can not cut toughened glass, so we will need to replace the unit (worth hanging on to the double glazed unit we take ut as should you move or need to put this back at a later date will save you some money).
Yes - as cat flaps come in different sizes, models, automatic etc. it is best to talk to us first in order that you can ask all the questions you require answered on the most popular brands. We offer a selection of cat flaps and pet doors, we highly recommend that you take a brief look at the options prior to making a decision. We have added a link from our site to some of the most popular brands.
It varies, but usually takes around 1 hour to install a cat flap in wood, UPVC, metal or a composite door, if it is a cat flap in glass or a double glazed unit, the glass will be toughened safety glass and usually take 3-5 working days to remanufacture and about 30 minuites to install again subject to type and style of door or frame.
We're afraid not as the glass is already toughened when you try to cut it and the glass would break into hundreds of thousands of pieces!
By providing a photo of the glass we can give you the exact price. If you are unable to provide a photo of the glass, then kindly provide some rough dimensions. Please measure from edge of glass to edge of glass you can see left to right and top to bottom.
Just be prepared to be a bit more patient with older cats who may not have used a cat flap before. Use a food reward for your cat and try playing in close by so they get used to being nect to it. Leave the flap open so they can see outside as curiosity will entice them closer until they eventually go through it.
No - The cat flap/catflap must be glass fitting and circular as it is very expensive to cut a square hole, although not impossible.
Cat flaps come with a kit that includes a paper template that guides you exactly where to drill. With the help of markings, drill a hole in to each corner of the template. Once you have done with drilling the holes, you can get the shape of your cat flap accordingly. These are great for wooden, UPVC/plastic and metal doors, but would recommend a professionaal for anything to do with glass.
Do You Fit Into Cavity Walls.
We DO NOT install through cavity walls; we recommend that you hire a professional builder for this type of installation.
Cat flap installation in a brick wall has many pitfalls; it is messy, expensive and time-consuming. there may be pipes or wires we can not see.
If this is your preferred route or only option you have for your home, we strongly advise you to consult with a qualified builder before considering installing a pet door through a wall, always ensure they have relevant building experience, qualifications, insurance and that they can comply with all building regulations.
