How long does it take for amoxicillin to start working in cats?
If your vet has prescribed amoxicillin for your kitty, you might be wondering how long it will take for the medication to start working.
The short answer is that it can take anywhere from 24-48 hours for amoxicillin to start showing its effects in cats. However, the actual time frame can vary depending on a few different factors, such as your cat’s overall health, their weight, and the severity of the infection.
Keep in mind that amoxicillin is a type of antibiotic that works by killing the bacteria that are causing your cat’s illness. So, it can take a little bit of time for the medication to build up in your cat’s system and start doing its job.
Note that amoxicillin is typically given twice a day, so sticking to the schedule is crucial for ensuring that the medication is able to do its job effectively. If your cat is still feeling poorly after a few days, it’s always a good idea to give your vet a call and discuss any concerns you may have.
What are the side effects of amoxicillin for cats?
Not all cats will experience side effects from amoxicillin, and the severity of side effects may vary. It is important to consult with a veterinarian before administering amoxicillin to cats and to monitor for any side effects during treatment.
Gastrointestinal upset: Common side effects of amoxicillin in cats include vomiting, diarrhea, and loss of appetite. These symptoms may occur due to the antibiotic disrupting the normal gut flora, leading to an upset stomach.

Overgrowth of resistant bacteria: Amoxicillin may lead to the overgrowth of resistant bacteria in the gut, which can cause further infections and make it more difficult to treat future bacterial infections.
Increased risk of Clostridium difficile: Amoxicillin can cause changes in the gut microbiome, which can increase the risk of Clostridium difficile infection.
Can I use human amoxicillin for my cat?
As a cat owner, it’s important to understand the differences between human and feline medications. While human amoxicillin may seem like a cost-effective solution for your cat’s illness, it’s actually not recommended. Here’s why:

Compounding pharmacies: Some compounding pharmacies can prepare custom-made amoxicillin formulations for cats, without the need for a prescription. However, it is important to ensure that the compounding pharmacy is reputable and that the medication is prepared under strict quality control guidelines.
