No matter how in-tune you are with your cat’s health, it’s not always easy to spot some of the illnesses that they may have under the surface.

While it’s important to keep an eye on their eating habits, their toilet behavior, and any signs of afflictions, there are plenty of problems that can come about that lie beyond your ability to recognize them.

Even worse, your cat is unable to communicate more complicated issues that they may be having, so it pays to be a vigilant owner.

They may have behavioral issues, such as isolation from other animals (or you), or issues with their sleep patterns. They may have become overly anxious, which can be symptomatic of other problems such as hair loss and dietary complications.

While none of these issues are fatal per se, symptoms such as these can kick start a chain reaction of misery, should the biological imbalance (or the outside elements) not be readjusted and amended.

What Is Melatonin?

Melatonin is a hormone that mammals produce naturally from glands in their body. Biologically, this chemical is secreted by the pineal gland (near the base of the brain) and helps to regulate the body’s natural clock. This helps everything from circadian rhythms to maintaining a regular sleep pattern. It tends to have a sedative effect, calming down the processes of the body.

Supplements of melatonin (for cats and other animals) can be given in the form of tablets, and liquid capsules to give an additional boost. The reasons one may give them (or take them for themselves) are many.

Can You Give a Cat Melatonin – Can Cats Have Melatonin?

Much like in humans, melatonin for cats helps to combat sleep disturbances. These tend to arise when a cat has experienced a stressful event such as the introduction of another animal to its territory, being moved to a new territory, or any other kind of trauma. So you are probably wondering – is melatonin safe for cats?

Much like digestion issues and hair loss, sleep deprivation is a sign of stress. As well as combating hair loss by stopping cats from excessively grooming themselves (another sign of stress), over the counter cat sedative for grooming can also stimulate the growth of new fur.

Human beings often take melatonin as a sleep aid and it can act as a sleep aid for cats, too. 

It can help with more chronic diseases too, such as Chronic Dysfunction Syndrome, which one other than describes as:

“The most common signs of [Chronic Dysfunction Syndrome] can be remembered by the acronym DISH: […] Disorientation, less social Interaction, altered Sleep patterns, and House soiling. It’s unusual to see all four signs in an animal, and the diagnosis can be made on the basis of only one sign”.

Cats may also require the sedative effects of melatonin should they experience general behavioral issues. Hyperactivity, or even latent aggression, can all be mitigated with melatonin.

In older cats that don’t have these concerns, they might instead experience ‘cognitive dysfunction’. Melatonin for older cats can help them redress their body clock.

Melatonin for Cats Dosage

You can get cat sedatives over the counter or “sleeping pills for cats” in your nearest pharmacy. However, cat melatonin dosages can vary wildly between cats, let alone from humans to cats. So how can you give cats melatonin? Before reading the side of the bottle and making your own adjustments, you should consult a trained vet before you try melatonin for cats.

The prevailing wisdom seems to be around 0.75mg per dosage. Pet Shrink goes into more detail:

“… For a cat, I’d probably start with about 0.75 mg [of melatonin]. Dose to be repeated as needed up to three times a day.” 

However, your cat’s age and weight, as well as other factors may come into play. Side effects may include weight-loss and increased lethargy.

They can also react adversely with other medications, which may cause an intolerance to other medications, or even an allergy to the melatonin itself. That said, too much melatonin may not be good for your cat.
