Why do some other cats try to use your cat flap?

Cats will try to use your cat flap for several reasons. The main one is greed. They are natural scavengers and typically eat small amounts regularly. If they are restricted to 2 or 3 meals by their owner rather than free feeding they are likely to feel hungry between meals.

This means if they see an opening in your front door they are likely to want to pop in and see what food they can pick up. This is made even worse if they can smell the food from outside and see it’s easy to get in.

What could happen if another cat comes into your home through the flap?

If another cat lets itself in it could try to claim your home as its own territory. This could result in it spraying your home. Also, studies have found that cats that have a cat flap that can be entered without a stag or chip are much likelier to be sprayed by their own cat.

Could a toddler fit through a Pet door?

There is a chance that a toddler could fit through a pet door. But, these are more likely to be pet doors designed for a dog rather than a cat. However, anything is possible. The best thing to do is to evaluate the risk with your family’s needs.

To mitigate this risk you can also look for a smaller pet door or locate it in a place that your toddler is not likely to venture to. The latter could be harder than you think, but the former is possible.

Obviously, if you have large kids this is not a concern. Another concern with these pet doors is burglars. They can use these holes to get into homes if they have the right skills.

Why won’t my cat use the Catflap?

Sometimes a cat will refuse to use its catflap because it does not feel comfortable with it. This can be helped by adding their scent to it.

This may sound weird initially, especially if you are new to cats, but their scent is what makes them identify what is their property. And, by doing this simple thing, you could make it more likely to use it.

Admitiantly, it may not happen overnight. But, with time it can make a big difference.

Can you put a cat flap into a metal door?

Can I put a cat flap in an internal garage door?

If you have a garage connected to your home you can either have a cat flap in the door leading to the garage or the garage door itself.

However, in most cases, the idea of a cat flap on the internal door leading to the garage, on its own, is not a good idea because the cat has nowhere to go once it’s through the door. Unless you want your cat to have access because you have food or litter there.

If you decide to do the latter, placing the flap on the garage door, it will allow the cat to gain access to the outside.

But, bare in mind, you may need a flap on the garage door and the internal door leading to the garage to provide full access to the outdoors.

Does a cat flap devalue a house?

A cat flap could devalue your home because it may appeal to a smaller demographic. However, it depends on the buyer’s needs. At a minimum it will change the interested buyers. Fortunately, there are many cat owners that could benefit from it.

A buyer that has no need for the flap may see it as a hassle because they either need to live with it or immediately replace the door, which adds to their post sale costs.

Should I lock my cat flap at night?

You should only lock the cat flap at night if you wish to keep your cat indoors. It is not advisable to lock your cat out. Instead, you could invest in a flap that scans the microchip in your cat and only allows access to them.

This way you can lock out other stray cats, and give your cat access all hours of the day and night.
