How Much Benadryl Can I Give My Cat?

What is Benadryl? To humans, whenever we feel an allergy kicking in, it’s easy to pop up a Benadryl to combat the allergy. Apparently, cats can also take Benadryl! If you’re still wary, I’ll get to the details of the answer to your question: How much Benadryl can I give my cat?


Can cats take Benadryl?

Sure they can! But only for the following conditions. Benadryl works for cats the same way it does for humans. It will also block the effects of histamine, such as a runny nose and itching. It is sort of like a quick fix! Make sure to take a look at this list well, before administering the medication to your cat

  1. Allergies.
  2. When your cat is bitten by insects or bugs.
  3. The appearance of rashes and other skin irritations.
  4. When your cat’s nasal passageways are congested.
  5. To help ease motion sickness.

Safety first!

Now if you’re asking how much Benadryl can I give my cat? Then there is no definite answer to that because there is no single dosage for all cats since all cats are different.

Here is a more helpful guide for you, to better see and understand what I am saying. If your cat weighs around 6.6 pounds (3 kg), you can give a 6 mg dosage of Benadryl as medication. A cat weighing 8.8 pounds (4kg) should be given an 8 mg dosage of Benadryl. An 11 pound (5 kg) cat should only get around 10 mg of Benadryl. Just do the rest of the math and see how much you should give your cat. 

Your cat may experience the following side effects:

  1. Disorientation.
  2. Drowsiness.
  3. Breathlessness and panting.
  4. Some experiences little seizures.

Consequently, if you notice your cat experience the following, contact your vet fast!

  1. Vomiting and diarrhea.
  2. Foaming at the mouth.
  3. Loss of appetite.
  4. Dilation of pupils.
  5. Doesn’t urinate quite as often.

Keep in mind

The standard and safe dosage for Benadryl is one milligram (1 mg) per one pound (1 lb) or two milligrams (2 mg) per one kilogram (1 kg), administered twice a day.

Prevention is also cure

It is also possible to not rely on Benadryl all the time. Find out which triggers your cat’s condition, and address that problem. Here are some ways to do so:

  1. Keep the air they breathe clean and allergen free.
  2. Try changing their litter to litters that have more adaptive properties to address allergies.
  3. You can also do something about the cat food they eat.

Round Up 

Since Benadryl is a drug, it is always safe to consult your vet before giving any to your cat. Look up the conditions where Benadryl isn’t advisable for use and how will it react when used with other medications. Self-medication is harmful in humans and in animals as well.
