Updated on

Can't decide how much penicillin to give your adorable four-legged friend? Too much intake can cause death to the feline, so knowing the right amount is both necessary and essential. No biggies - you've come to the right place! So, keep on reading!

Cats surely know how to hide their pain, but some noticeable signs tell you if they suffer from poor health condition - may be due to viral attack, bacterial infection, or something fungal.

If you notice your feline has fever or diarrhea, he may have contracted a bacterial infection. You can give him penicillin. However, the question of how much should you give penicillin to a cat comes up.

What is Penicillin and How It Works?

A general antibiotic, penicillin has a restricted range of activity, and various types of bacteria have acquired resistance to this medicine. This is why vets usually recommend penicillin when they're entirely sure that it will give a valid result when combined with other drugs or against a particular infection.

If combined with its extensive spectrum activity and low side effect profile, penicillin is such an excellent choice for curing respiratory, ear, soft tissue, urinary tract, and skin infections among cats.

It is commonly given through injection, though some types are injected under the skin or in a muscle, while others are injected into a vein. Penicillin interrupts the bacteria's cell walls and prevents them from producing a functional cell wall as soon as they breed.

When to Use Penicillin for Your Cat?

It is not necessary to get penicillin when you notice something is off about your cat. Knowing the frequent use of this drug is highly essential. Its use on your cat is limited to soft tissue infections, ear infections, respiratory infections, and skin infections.

It is not common for felines to get a prescription even when your veterinarian has yet to accurately determine the type of infection while waiting for the lab result.

If your cat is pregnant, you may think twice about getting penicillin. You can talk with your vet regarding this matter..

The Type of Penicillin You Need to Use

There's essentially an extensive array of penicillin in the market, including:

Natural penicillin - widely recommended for meningitis, strep throat or other oral infections.
Penicillinase-resistant penicillin - commonly prescribed for staph infections and deals with thinner spectrum.
Aminopenicillin - effective towards the obliteration of gram-negative bacteria.
Extended-spectrum penicillin - works the same with aminopenicillin but have a wider spectrum.

Above are all good options for treating certain infection in cats, but amoxicillin (a new type of aminopenicillin) stands out among the rest because it comes with natural acid resistance. This means, you don't have to take your cat to the veterinarian for daily shots - you can merely give one orally at your home.

How Many Dosages of Penicillin to Give a Cat?

Now, we've come to the core of the topic. There are numerous factors to consider, which include the age and weight of the cat, the severity, and the type of infection being treated.

For instance, if your cat is 9.9 pounds, you should give him 1/2 - 1 tablet size of penicillin. Those cats with a weight of more than 4.96, a 1/2 tablet size is needed. Ask your vet about the right dosage to avoid potential risks.

Are There Possible Side Effects?

Well, yes!

Among the side effects, you need to watch out for include:

  • Itchiness
  • Vomiting
  • Diarrhea
  • Facial swelling
  • Difficulty breathing
  • Loss of appetite
  • Joint pains
  • Hives and another form of skin rashes
  • Liver or kidney damage

Gastrointestinal upset and anaphylaxis (a severe type of allergic reaction) are the most serious side effects. To reduce the side effects, administer the drug during mealtimes.

How to Give Your Cat a Shot of Penicillin

Before you start, ask the vet for training and advice on how to properly administer the medicine. 

Administering tablets:

  • Mix with food and serve it to your cat.
  • Hide the pills in semi-wet or wet food areas in which liquid penicillin blends in dry treats.

Administering liquid penicillin:

  • Mix also with food and then serve.
  • The food must be way beyond pill proportion-size so your cat would be lured to eat it.

Follow the schedule given. Make sure your feline gets his medicine on a regular basis and at the chosen times too. Even he is no longer showing any symptom of being sick, ensure to stick to the timetable.

Giving penicillin to your cat needs confidence, skill, and patience. If you think you're not capable of doing the job properly, don't afraid to ask help from your veterinary care team.

To Wrap It Up

Penicillin can be used almost anything and anyone. However, do not overlook the professional help of a vet especially when giving a dosage to your cat.
