Melatonin For Cats – Is It Safe?

Cats spend almost two-thirds of their lives sleeping and any disruption could mean certain physical or mental issues. Melatonin is an over-the-counter drug/supplement that you can purchase to help ease your kitty and help them snooze. However, this should only be given with the recommendation of your vet.

Can you give cats Melatonin? The answer is YES.

There are many ways to administer this supplement and we’ll be discussing them so make sure you read further.

Cats usually take most of the day sleeping and any difficulty in doing so could be signs of impending physical or mental illnesses. They can also experience problems such as anxiety, depression, stress, etc. Here are the possible causes:

  • Change in sleeping area
  • Reduced food intake
  • Dominance by the other pet
  • Excessive noise
  • Physical sickness (stomach upset, diarrhea, cancer, etc.)

Symptoms of sicknesses and diseases can easily be spotted. However, if you feel that the only symptom your cat is showing is its restlessness, then you are strongly urged to visit the veterinarian to check what’s happening to your kitty.

Vomiting, hair loss, and reduced food intake could pair with sleep deprivation. These could be caused by many sicknesses and any attempt to pinpoint the culprit on your own is basically futile. Get your pet checked and see what could be the reason behind these symptoms.

Giving your house a total makeover (including your pet’s sleeping place) could trigger discomfort in cats which could lead to insomnia. Prior to making any changes, you should note down the places where your kitty gets uneasy and remember to avoid placing any pet-related item there.

Buying another pet could also be one of the reasons why your fur baby is uncomfortable. An addition to the family would more likely leave the cat feeling dejected and could affect its eating, sleeping, even playing patterns. Your new cat/dog might be exercising too much dominance which takes a toll on your kitty’s confidence.

Here are some of the changes that could result from animal dominance:

  • Reduced eating habits – the other pet could be hogging all the food
  • Change in sleeping area – some cats could also take over your pet’s territory which forces it to move and experience discomfort
  • Reduced activities and interactions – having a new kitty could dishearten the first one and stop interacting with you. These are the usual signs of stress and depression
  • Constant “Meowing” – cries from your pet always have a meaning. You can stop the pet rivalry by giving them different areas to sleep, different eating times, and their own playtime with you.

You can try to train them together. Giving them disciplinary lessons could help them come to terms with having other animals around and trust exercises could help them solve their differences.

Try noticing the area where you place your cats. Is there too much noise? Are they too close to the window that any type of scratch disturbs their sleep? Maybe it’s time to move them away from anything that could interrupt their peace.

Try placing them near the closet or at the foot of your bed. Cats are more comfortable sleeping near their masters (or on the owner’s bed to be more accurate).

Providing your cat medicines isn’t the only way to help induce its sleep. There are other methods such as therapy, massages, soft music, and fluffy pillows but some vets recommend a small melatonin dosage for cats.

The dose would depend on the reason of medication and the size of your pet. In some cases, kitties are given around 0.5 mg – 0.8 mg while others get 1.6 mg or more every 12 hours. The vet will also instruct you to take note of any adverse reactions that may arise.

Skin abrasions can also take effect if your cat is allergic. If you see such symptoms, then stop administering the supplement and see your vet immediately.

The main benefit of this drug would be its aid in inducing sleep. Most cats who deal with mental problems find it very hard to maintain their inner peace thus the difficulty in snoozing.

Some cats are given Melatonin through tablets, some through liquid gels, and others through chewable treats. It can also be added to their diet upon the recommendation of the vet if the problem is recurring.

Here are some of the brands that include Melatonin:

  • NaturVet Quiet Moments
  • VetriScience Pro Bite
  • Mela-Vet Soft Chews
  • Particular Paws Cat Calming Aid

Not only does it help your pet get some ZZs, it can also help regulate the immune system. Melatonin comes as an ingredient in most cat supplements which also contain other vitamins and minerals.

Some side effects of this supplement could be hormonal imbalance, increase in appetite, changes your cat’s heat cycles, etc. These situations help in regulating your pet’s hormones as they stray them away from the thought of reproduction.

What’s the Bottom Line?

We all agree that Melatonin could be good for problematic cats as long as you give them the right dosage. Though it does not cure sicknesses, it can help calm down your felines in order for you to find the right solution if their condition is more than what meets the eye.

Sick cats may be taking more than one medicine at a time so make sure to list all of them down and check with your vet to see if Melatonin would react to any of the drugs being taken. Failure to do so could result to intolerance or allergies to different types of medication.
