Important Features To Consider

A cat thermometer should be able to accurately read your cat’s temperature, have decent battery life, and be comfortable for your cat. Here’s what to consider when selecting a thermometer for your cat.

  • Accuracy. The most important feature when using a cat thermometer or any kind of thermometer for that matter is the accuracy of the temperature that is taken. One of the features to look for in a cat thermometer when shopping for one is the accuracy range of it. To what degrees do they properly assess? If it is not between within +/- 0.2°F, you may want to look into a different cat thermometer. Accuracy of temperature taken is the single most important feature to look for when searching for a cat thermometer.
  • Comfort. Overall, taking your cat’s temperature should be a comfortable experience for them. Even though they may be a little scared at first, taking their temperature should not be painful for them at all. When you are looking for a good cat thermometer, try to find one that you think your cat would be most comfortable with, because, after all, you know your cat and their temperament the best. While plenty are rectal thermometers, there are also other options such as auricular (ear) or axillary (underarm) thermometers. However, rectal usually does give the most accurate reading.
  • Battery life. The last thing that you want is when you go to take your cat’s temperature, the batteries die right in the middle of it. Then you have to fiddle with it, and try to find the cat again. Look for a thermometer that has a good battery life or one that perhaps maybe rechargeable via USB or wall charger. Always make sure that you also purchase extra batteries when buying a cat thermometer so you can have them on hand when the batteries do die. It is important to check them regularly.

Frequently Asked Questions

How do you take a cat’s temperature?

The most accurate way to take a cat’s temperature is by using a rectal thermometer. While other types of thermometers may work, the rectal temperature will give you the closest reading. In order to take a cat’s temperature, you may want to have a helper with you to help keep your cat calm, depending on whether or not your cat is skittish. To take their temperature you will need a few things. The thermometer itself, lubricant jelly, a cat treat, and isopropyl alcohol and a paper towel. To begin, you need to lubricate the tip of the thermometer with the lubricant jelly. If you have a helper, have them help to restrain your cat and keep them calm. If you are by yourself, hold your cat firmly against you with one arm. Next, lift the tail and slowly insert the thermometer into the anus, gently moving it from side to side in order to get the muscles to relax. Once they do, insert the thermometer about one inch, however, do not force it if it will not go past a certain point. When you hear a beep, you may pull out the thermometer and you will then be able to tell whether or not your cat has a temperature. If they have not been vomiting, give them the cat treat. Use the paper towel and alcohol to clean the thermometer.

Can you take a cat’s temperature with a human thermometer?

Certain thermometers that are indicated for use on humans can be used on cats. However, before you measure your cat’s temperature with that digital thermometer you have, you may want to check with your veterinarian to make sure that it is safe to use it.
