What is Gabapentin?

Gabapentin, initially developed for human use in managing epileptic seizures and neuropathic pain, has found its place in the veterinary world due to its calming effect on animals. It works by calming overactive nerve impulses, hence its effectiveness in reducing anxiety and promoting relaxation in our feline friends.

Dosage Considerations

The gabapentin dosage for cats largely depends on the individual cat’s weight, its overall health status, and the intended use of the drug. When used for sedation, a common dosage is around 100 mg per cat, given a few hours before a potentially stressful event such as a vet visit. However, this can vary, with some sources suggesting a range of 10-40 mg per kilogram of the cat’s body weight.

Remember, it is crucial to follow the veterinarian’s advice on the appropriate dosage for your cat, as they would consider all necessary factors, including the cat’s overall health and age.

Safety and Side Effects

Though gabapentin is generally well-tolerated by cats, like any medication, it’s not without potential side effects. These can include drowsiness, loss of coordination, and occasionally, gastrointestinal issues. Monitoring your cat’s behavior and reactions after administration of gabapentin is essential to quickly address any adverse effects.

How to Administer Gabapentin to Cats

Getting a cat to take medication can often feel like an Olympic sport! If gabapentin is recommended by your vet, you’ll be glad to know it can be disguised in food. It’s generally available in capsule form, which can be opened and mixed with your cat’s favorite wet food. Make sure your cat consumes the entire portion to get the full dose.


While gabapentin can be a valuable tool for feline sedation and stress reduction, it is essential to use it responsibly and under the guidance of a professional veterinarian. Every cat is unique, and what works for one might not work for another. By understanding the ins and outs of gabapentin, you’re taking a step towards a less stressful vet visit for your beloved feline companion.


1. Is gabapentin safe for all cats?

While gabapentin is generally safe for most cats, there are exceptions. For example, cats with kidney disease may require a modified dosage as gabapentin is primarily excreted through the kidneys. Furthermore, it’s vital to note that each cat may react differently to medication, and what works for one may not work for another. Always consult your vet before introducing new medications.

2. How quickly does gabapentin work in cats?

The calming effects of gabapentin usually become apparent within one to two hours post-administration. Its peak effects occur around three hours after ingestion, making it important to time administration appropriately before a stressful event or vet visit.

3. Can gabapentin cause negative side effects in cats?

While generally well-tolerated, gabapentin may cause side effects in some cats. Common side effects include sedation, wobbliness, and sometimes, vomiting or diarrhea. Should your cat exhibit any unusual behavior or symptoms following its administration, reach out to your vet immediately.

4. Can I use human gabapentin for my cat?

While the active ingredient is the same, it’s essential to use the medication prescribed by your vet. Certain formulations of human gabapentin may contain additives or sweeteners, like xylitol, which are toxic to cats.

5. Can my cat develop a dependence on gabapentin?

Unlike some other sedatives, gabapentin does not typically lead to dependence or withdrawal symptoms in cats. However, any long-term use of medication should be under the close supervision of your veterinarian.

6. Can gabapentin be used in conjunction with other medications?

Gabapentin is often used in combination with other medications for managing chronic pain or anxiety in cats. However, it’s crucial to consult with your vet before introducing any new medications to ensure there’s no risk of harmful interactions.

7. What should I do if my cat misses a dose of gabapentin?

If your cat misses a dose, give the missed dose as soon as you remember. If it’s close to the time for the next dose, skip the missed dose and return to the regular dosing schedule. Never double dose to make up for a missed one. Always consult your vet if you’re unsure.

8. What should I do in case of a gabapentin overdose?

If you suspect your cat has ingested an excessive amount of gabapentin, seek veterinary care immediately. Symptoms of overdose can include severe lethargy, depression, or in more severe cases, respiratory distress. Immediate veterinary intervention can make a significant difference in outcome.

9. Can gabapentin be used for long-term treatment in cats?

Gabapentin can be used for long-term treatment in cats, especially for managing chronic pain or anxiety. However, long-term use should be under the strict supervision of your veterinarian to monitor your cat’s health and adjust the dosage as necessary.

10. How should gabapentin be stored?

Gabapentin should be stored at room temperature, away from light and moisture. Avoid storing it in a bathroom or any area prone to dampness. Keep it out of reach from pets and children to prevent accidental ingestion.

11. What should I do if my cat refuses to take gabapentin?

If your cat refuses to take gabapentin directly or mixed with their food, consult with your vet. They may suggest alternative methods of administration or switch to a different medication with a similar effect.

12. How does gabapentin help with stress during vet visits?

Gabapentin has a calming effect on cats, reducing anxiety and promoting relaxation. Given a few hours before a stressful event like a vet visit, it can help make the experience more tolerable for your feline friend.

13. Is gabapentin used only for sedation in cats?

While this article focuses on gabapentin’s use for sedation, it’s also commonly used in managing chronic and neuropathic pain in cats. It can also be beneficial for cats with seizure disorders.

14. Can gabapentin be used for kittens?

The use of gabapentin in kittens is generally safe, but the dosage would be significantly lower than that of an adult cat and should always be determined by a vet.

15. What happens if gabapentin treatment is stopped abruptly?

While gabapentin doesn’t typically cause withdrawal symptoms in cats, it’s always best to gradually reduce the dosage rather than stopping abruptly. This allows your cat’s body to adjust and can help prevent any rebound effects. As always, consult your vet before making any changes to your pet’s medication regimen.

16. Is gabapentin a controlled substance?

Gabapentin is not a federally controlled substance in the United States. However, it is classified as a controlled substance in certain states due to potential human misuse. Despite this, it is a prescription medication and should only be used under the direction of a veterinarian.

17. Can gabapentin be used as a routine calming aid for cats?

While gabapentin can certainly help manage anxiety and promote relaxation in cats, its use should be discussed with your vet. Regular use without appropriate supervision could lead to unnecessary side effects or mask symptoms of underlying issues causing anxiety.

18. What should I observe in my cat after administering gabapentin?

After administering gabapentin, monitor your cat for signs of relaxation and possible side effects. Observe for unusual lethargy, trouble walking, loss of appetite, or any other changes in behavior. Contact your vet if you have any concerns.

19. Are there natural alternatives to gabapentin for calming cats?

Yes, there are natural alternatives such as Feliway, a synthetic pheromone spray that can help reduce stress and anxiety in cats. Calming diets and supplements are also available. However, these may not be as potent as gabapentin and should not replace prescribed medication without your vet’s approval.

20. Can I give my cat gabapentin if she is pregnant or nursing?

The safety of gabapentin in pregnant or nursing cats is not well-studied. Therefore, it should only be used in these cases under the direction of a veterinarian who can weigh the potential risks and benefits.

21. Can gabapentin interact with other medications my cat is taking?

Yes, gabapentin can interact with certain medications, such as antacids and some pain relievers. Therefore, it’s important to inform your vet about all medications, supplements, or over-the-counter drugs your cat is currently taking.

22. Is it possible for my cat to build up a tolerance to gabapentin?

While the development of tolerance (requiring higher doses for the same effect) is common with some medications, it’s less common with gabapentin. However, if you notice that gabapentin’s effectiveness is diminishing, contact your vet. Do not increase the dose without veterinary guidance.

23. Does gabapentin treat the underlying cause of anxiety in my cat?

Gabapentin can help manage symptoms of anxiety but doesn’t address the underlying cause. Additional behavioral modification, environmental changes, or other therapeutic interventions may be necessary to treat the root cause of anxiety.

24. Can gabapentin be used in multi-cat households?

Yes, gabapentin can be used in multi-cat households, but remember that each cat is an individual and may require different dosages. Always consult with your vet about the specific needs of each of your feline friends.

25. What’s the difference between human and veterinary gabapentin?

While the active ingredient in both human and veterinary gabapentin is the same, the formulation may differ. Some human forms may contain ingredients harmful to cats. Always use the formulation prescribed by your vet for your cat’s safety.
