Sleep and Senior Cats—Why Is My Old Cat Not Sleeping?

Common Sleep Issues in Older Cats

It’s not unusual for an old cat not sleeping well to show signs of restlessness, nighttime vocalization, or changes in their sleep-wake cycle. Causes can include:

Cognitive changes or feline dementia
Arthritis or discomfort
Anxiety or changes in routine
Medical conditions (hyperthyroidism, kidney disease)

Can Supplements Improve Sleep in Older Cats?

Supplements with calming ingredients (like L-theanine or fish oil) and those supporting cognitive function (like NMN) may help regulate sleep patterns. Always consult your vet if your old cat is not sleeping, as underlying medical issues should be ruled out first.

For many, the answer to “do older cats need supplements” is yes—especially for sleep and cognitive support.

Is NMN Safe for Cats?

NMN (nicotinamide mononucleotide) is a molecule that helps boost NAD+ levels, supporting cellular health, energy, and longevity. But is NMN safe for cats?

Research: Early studies and real-world use suggest NMN is generally safe when formulated for cats and dosed appropriately.
Purity: Choose supplements tested to human-grade standards, free from fillers or contaminants.
Vet Guidance: Always consult your veterinarian before starting NMN or any new supplement.

Never give human NMN supplements to cats—use only feline-specific formulas.

NMN Dosage for Cats—Getting It Right

How Much NMN Should You Give a Cat?

Typical Dosage: Most felines, NMN supplements should deliver approximately 80mg of NMN per day.
Start Low: Begin with the lowest recommended dose and monitor for positive changes.
Consistency: Results often appear after 2–4 weeks of daily use.

Signs Your Cat May Benefit from NMN

Reduced energy or playfulness
Cognitive changes (confusion, altered sleep)
Visible aging or joint stiffness

The right NMN dosage for cats is always based on weight, age, and individual health status.
