FAQs on Gabapentin Dosage for Cats

What is Gabapentin and Why Is It Given to Cats?

Gabapentin, originally developed to treat seizures in humans, has found its niche in veterinary medicine for pain management and anxiety reduction in pets, especially cats. It’s especially useful for cats with chronic pain or those that get anxious during vet visits or car rides.

Understanding the Correct Dosage

General Dosage Information: While the optimal dosage varies based on the cat’s size, weight, and health condition, it generally ranges from 5-20 mg/kg.

For Anxiety: A common dose for anxiety or behavioral issues might be 100mg for an average-sized cat, given a couple of hours before a stressful event, like a vet visit.

For Pain Management: For pain, the dose might be split, with the cat receiving 100mg twice a day.

It’s All About Weight: Keep in mind that dosages can vary depending on the weight of the cat. The general rule of thumb is 2.5-5mg per pound of body weight.

Factors Influencing Gabapentin Dosage in Cats

Purpose of Administration: Whether you’re giving Gabapentin for pain relief or anxiety will influence the amount prescribed.

Individual Cat Needs: Just like humans, cats respond differently to medication. Some might need a higher dose for the desired effect, while others might do well on a lower dose.

Age and Health: Senior cats or those with kidney issues might require a modified dose.

Tips for Administering Gabapentin to Cats

Use Pill Pockets: Cats can be notorious for refusing medication. Using pill pockets can help disguise the medicine, making it easier to administer.

Liquid Form: If your cat refuses pills, ask your vet for a liquid version of Gabapentin.

Mix with Food: Some cats accept the medicine when it’s mixed with their favorite wet food. However, ensure your cat consumes all the food to get the full dose.

Safety Precautions and Side Effects

Always follow your vet’s recommendation for dosage and administration frequency.

Monitor your cat after giving Gabapentin, especially the first few times. Some cats might experience sedation or, in rare cases, more severe reactions.

Avoid abrupt discontinuation. If you need to stop the medication, consult your vet for a tapering plan.


When administered correctly, Gabapentin can be a life-changer for cats experiencing pain or anxiety. Always work closely with your vet, be observant, and adjust as necessary to ensure your cat’s health and safety.

While Gabapentin is typically administered orally in cats, compounding pharmacies can create a topical gel. This is a specialized formulation, so discuss with your veterinarian if this route is appropriate for your feline friend.

Gabapentin typically calms anxious behavior in cats, but it doesn’t change their underlying personality. Once the medication wears off, your cat should revert to its usual behavior.

18. Can I split Gabapentin capsules for my cat?

If your cat requires a dosage that isn’t readily available, you might be tempted to split a capsule. However, ensure the splitting provides an accurate dose and that your cat receives the full amount. Talk to your vet or a compounding pharmacy for tailored dosage solutions.

20. Can Gabapentin be used in conjunction with other pain relievers?

In some cases, Gabapentin can be combined with other pain relievers for enhanced pain control. This is often termed “multi-modal pain management.” Always ensure such combinations are vet-approved to avoid harmful drug interactions.

Gabapentin is excreted through the kidneys, so cats with compromised kidney function may require adjusted dosages. Regular kidney function tests are advised for cats on Gabapentin, especially if on it for an extended period.
