DERMATONIN IMPLANT FOR CATS
Melatonin acts as a natural, reversible suppressor of the estrus (heat) cycle in female cats by simulating short-day sunlight conditions, effectively delaying or inhibiting breeding
Dermatonin (melatonin implant) is A long-acting subcutaneous implants (approx.
18 mg AND 24 mg) to control, rather than enhance, reproduction, often lasting
2–4 months.
- Mechanism: Cats
are long-day breeders; high melatonin levels (simulating short
days/winter) inhibit the, hypothalamus-pituitary-gonadal axis and suppress
ovarian activity.
- Effectiveness: Studies
show that melatonin implants are a safe, temporary, and effective
alternative for non-surgical reproductive control.
- Application: Small
implant placed near the belly button area or between the shoulder
blades.
- Uses: It
is used to delay or manage the "heat" cycle, reducing unwanted
behaviors associated with estrus.
- Considerations: While
generally safe with few side effects reported, it is primarily used for
short-term estrus suppression.
Cat breeders
Primarily use
melatonin (Dermatonin) as a reversible, non-surgical method to manage the reproductive
cycles of female cats (queens)
. Because cats are
"long-day breeders," their heat cycles are triggered by increasing
daylight; melatonin mimics the "short days" of winter to suppress
these cycles.
Key Uses for Breeders
- Estrus
(Heat) Suppression: It is used to temporarily
delay or stop heat cycles, allowing breeders to control the timing and
frequency of litters without permanent sterilization.
- Show
Competition: Purebred cats can be kept
"entire" (un-spayed) for Cat
Fanciers' Association (CFA) championship
eligibility while suppressing the vocalizing and restlessness associated
with heat.
- Male
Management: In tomcats, it may be
used to temporarily reduce sexual behaviors such as urine marking and
aggression.
Administration &
Methods
- Subcutaneous Melatonin Implants (Dermatonin): A common veterinary
approach involves melatonin implants placed under the skin. These are
designed to suppress estrus for a period of time.
- Reversibility: Melatonin implants are considered reversible, and cats typically return to their normal
reproductive cycle once the effects wear off.
Key Considerations for Male Cats
Male cats generally
react to melatonin with increased drowsiness and sedation, as it is often used
for anxiety or sleep disorders. While typically safe for neutered cats, it can
lower semen quality and decrease testosterone in intact toms, acting as a potential
reproductive regulator. Potential side effects include mild digestive upset,
changes in appetite, or disorientation. National Institutes of Health (NIH) |

Sedation/Calming: The primary effect is reduced alertness and drowsiness, which can be useful for reducing anxiety or managing sleep-wake cycles.
- Reproductive
Effects: In intact male cats
(toms), melatonin can significantly decrease semen quality, including
reduced sperm concentration and motility.
- Safety
& Dosage: While generally safe,
always consult a veterinarian for the correct dosage. Avoid supplements
containing Xylitol or other toxic ingredients.
- Side
Effects: Rarely, cats may
experience vomiting, diarrhea, or changes in appetite.
Health Considerations: Cats with pre-existing chronic conditions, such as diabetes or respiratory issues, should only take melatonin
