Size determination

How to determine the correct OPTIVIZOR mask size/variant for your cat:

Step 1

Determine head size

Measure the cat’s head circumference exactly in front of the ears from the middle of the ears, under the jaw and back (see Fig. 1). Attention: The measuring tape must fit tightly, even over the ears (which will later stick out of the mask!).

Then use the chart below for cats to determine the correct mask size.

Step 2

Determine weight

Then, using the weight of your cat in the second table, check which mask is suitable for the animal. Since cats come in all different sizes and shapes, according to the charts, there may be two different mask sizes for your cat. Then please choose the smaller one !

Step 3

You should now be able to decide on the right options “size”.

NOTE: Cats have very different head shapes and body mass. Therefore, it is very difficult to create a reliable, unambiguous measurement table. Ultimately, the proof of the pudding is in the eating. Please call us, we will be happy to advise you!
