Risks and Side Effects of Painkillers for Cats

All pain medications carry risks, especially for cats. Their unique metabolism makes them more sensitive to certain drugs. Here's what to watch for with common vet-prescribed painkillers.

MedicationCommon Side EffectsSerious RisksMonitoring Needed
Robenacoxib (Onsior)Vomiting, diarrhea, decreased appetiteKidney damage, gastrointestinal ulcersBlood work before and during use; short course only
MeloxicamLoss of appetite, lethargyKidney failure (especially in dehydrated cats)Hydration status, kidney function tests
GabapentinSedation, drowsiness, wobblinessRare; may worsen kidney disease at high dosesAdjust dose for kidney function
BuprenorphineSedation, euphoria, dilated pupilsRespiratory depression (rare)Monitor breathing and behavior
SolensiaMild injection site reactions, vomitingAllergic reactions (rare)Report any persistent symptoms to vet

Silent killers in cats include kidney disease and liver failure — both can be worsened by improper painkiller use. Always follow your veterinarian's dosing instructions exactly. If you notice any concerning symptoms, contact your vet immediately.

What Pain Relief Can You Give a Cat at Home?

While you should never give over-the-counter painkillers, there are safe ways to help your cat feel more comfortable at home before you can get to a vet. Follow these steps.

  1. Create a calm, quiet space — Reduce noise and activity. Provide a soft bed in a warm, dimly lit room where your cat can rest undisturbed.
  2. Offer gentle comfort — Speak softly and pet your cat gently if they allow it. Avoid handling painful areas.
  3. Ensure easy access to essentials — Place food, water, and litter box nearby so your cat doesn't have to move far.
  4. Use warm compresses (if approved) — For muscle pain, a warm towel on the area may help, but only if your cat tolerates it and you've checked with your vet.
  5. Do not give any human medication — Even natural supplements like CBD or turmeric should only be used under veterinary guidance.
  6. Schedule a vet appointment — Call Cats Only Clinic at (916) 435-9300 or walk in during our hours. We offer a free first exam for new clients.

Remember: home care is temporary. The only safe way to relieve your cat's pain long-term is with a proper diagnosis and prescription from a veterinarian.

Signs Your Cat Is in Pain and Needs Relief

Cats are masters at hiding pain, but there are telltale signs. Use this checklist to determine if your cat may be suffering and needs veterinary attention.

  • Hiding or withdrawal — Your cat may hide under furniture, in closets, or avoid interaction more than usual.
  • Changes in appetite or drinking — Eating less, drinking more, or refusing treats can indicate pain or illness.
  • Altered grooming habits — Over-grooming a specific area (licking, biting) or neglecting grooming entirely (matted fur) are red flags.
  • Vocalizing — Increased meowing, yowling, or purring (which can be a sign of distress) may mean discomfort.
  • Changes in litter box use — Avoiding the box, straining, or crying while urinating can signal pain, especially from urinary issues.
  • Limping or stiffness — Difficulty jumping, climbing stairs, or moving around normally suggests joint or muscle pain.
  • Aggression or irritability — A normally friendly cat may hiss, swat, or bite when touched if they are in pain.

If you notice any of these signs, contact us at Cats Only Clinic for an evaluation. Early treatment can prevent more serious problems.

Frequently asked questions

How long does meloxicam take to work in cats?

Meloxicam typically starts working within 1 to 2 hours after oral administration. It reaches peak effectiveness in about 4 to 6 hours. Your veterinarian will provide specific dosing instructions and monitor your cat for any side effects.

What are the potential side effects of Metacam in dogs?

This question is about dogs, not cats. For cats, meloxicam (the same active ingredient) can cause side effects like vomiting, diarrhea, loss of appetite, and kidney damage if not used correctly. Always follow your vet's guidance and report any concerns.

What is a silent killer for cats?

Kidney disease is often called a silent killer in cats because symptoms may not appear until the disease is advanced. Other silent threats include hyperthyroidism and dental disease. Regular vet check-ups can catch these issues early.

What are four signs your cat is suffering?

Four common signs of suffering in cats are: hiding or withdrawal, decreased appetite or thirst, changes in grooming (over-grooming or neglecting), and increased vocalization or irritability. If you notice these, seek veterinary care promptly.

What calms a cat down immediately?

Creating a quiet, dark, and safe space can help calm a stressed or painful cat. Soft bedding, gentle petting (if tolerated), and pheromone diffusers like Feliway may also help. For severe anxiety or pain, consult your vet for appropriate medication.
