Cat flap freezes


After winter outings, the cat comes through the cat flap at any time independently to warm up back to the safe house. In freezing temperatures, the flap can also freeze and lock out the cat. This problem can be avoided.

Cause condensation

In winter the interior of the cat flap is in the well-warmed house. The outer flap area is depending on the weather in minus temperatures. This large temperature difference between the two areas ensures a so-called dew point in the construction of the flap.

At this point, condensation forms. It accumulates and freezes at temperatures below zero degrees. Affected are usually also the closing and opening mechanisms of the cat flap. If they are frozen, the cat flap does not work anymore.

First aid with frozen cat flap

A frozen cat flap can be thawed by supplying heat. A radiant heater or a hair dryer are a good tool. Then the thawed condensation must be wiped away. All affected components of the cat flap should be rubbed thoroughly dry to delay re-feeding for as long as possible.

Since new condensation will form again and again at the dew point, the regular removal of the water is considered a troublesome but effective preventive measure.

Protection against freezing

The rubber parts of the cat flap are rubbed with Vaseline, talc or similar nontoxic and harmless agents. Freezing at low temperatures can be prevented. When choosing a remedy, always keep in mind that your cat will come in contact with it. When passing through the cat flap, remnants of it can settle in the fur and are later licked by the cat.

Cold and heat lock

The high temperature differences between indoor and outdoor area can be compensated by an external cold and heat lock. Depending on the design and insulation of such a lock, effort and costs can be enormous. The implementation is not possible on all cat flaps, as often lack the necessary space in the outdoor area.

Tips & Tricks

Never use antifreeze to prevent the cat flap from freezing. Antifreeze is highly toxic to humans and animals. Every year many dogs and cats die because they are negligently brought into contact with the remedy.
