Why Kittens Nurse on Each Other

Nursing on each other, or “non-nutritive suckling,” as it’s known in the veterinary world, can stem from several factors. It’s a behavior rooted in the kitten’s instinctive need for comfort and security, often manifesting when they’re separated from their mother too early or are in a particularly stressful environment. However, it can also be a sign of hunger, especially if the nursing kitten is not receiving enough nutrition.

During my second year of fostering, I encountered a pair of kittens, Luna and Artemis, who were inseparable. Artemis began to nurse on Luna’s ear, a habit that seemed harmless at first but gradually led to Luna’s discomfort and even a mild infection. This experience taught me the importance of understanding the root causes of such behavior, which can range from the need for comfort to nutritional deficiencies.

Separate the Kittens

While it might seem harsh, separation is sometimes necessary to break the cycle of nursing behavior. It’s not about isolating them completely but providing short breaks where they can relax without instigating the nursing behavior.

Use a Bitter Spray

Applying a safe, bitter-tasting spray to the area being nursed on can deter the behavior. It’s essential to choose a product specifically designed to be safe for pets, as not all bitter agents are kitten-friendly. The first time I used a bitter spray, I was skeptical, but the immediate cessation of nursing on the treated area was a revelation.

Insider Tip: Always conduct a patch test before applying the spray broadly to ensure your kitten doesn’t have an adverse reaction.

Distract the Kitten

Distraction can be a powerful tool. Offering a stimulating toy or engaging in playtime can redirect the nursing kitten’s attention and energy. I’ve found that interactive toys, like laser pointers or feather wands, work wonders in capturing kittens’ attention and drawing them away from nursing behaviors.

Use a T-shirt

Dressing the suckled kitten in a snug, kitten-safe T-shirt can provide a barrier to nursing while also offering them comfort. It’s a trick I stumbled upon by accident but has since become a staple in my kitten-care toolkit. The T-shirt not only prevents access but can also soothe the kitten by providing a gentle, constant pressure akin to being cuddled.

Provide a Nursing Toy

Some kittens need to suckle to feel soothed. Providing a nursing toy or a pacifier designed for kittens can satisfy this urge safely. This method was a game-changer for Artemis, who transitioned from nursing on Luna to cuddling with his nursing toy within a week.

Real-Life Case Study: Helping Kittens Stop Nursing on Each Other

I once had two kittens, Luna and Milo, who were rescued together. Despite being weaned, Luna kept nursing on Milo, causing discomfort and irritation. We tried separating them, but Luna would always find her way back to Milo. After researching, we tried using a bitter spray on Milo, which effectively discouraged Luna from nursing on him. Additionally, we provided Luna with a nursing toy, which redirected her nursing behavior.

This real-life case study highlights the effectiveness of using a bitter spray and providing alternative outlets for nursing behavior. It also emphasizes the importance of patience, as it took some time for Luna to fully stop nursing on Milo.

Give the Kittens Time

Patience is crucial. Sometimes, despite our best efforts, kittens may continue to nurse on each other until they naturally outgrow the behavior. In many cases, as kittens age and become more independent, the urge to nurse diminishes. It’s a reminder that, at times, time itself can be the most effective solution.

When to See the Vet

It’s vital to consult a veterinarian if the nursing behavior persists despite intervention or if there are signs of health issues such as skin irritation, infection, or weight loss in either kitten. A professional evaluation can help rule out medical causes and provide tailored advice. Understanding how long kittens stay attached to the placenta can also be helpful in assessing their early development stages.

In conclusion, while kittens nursing on each other can be a sign of underlying issues, it’s a behavior that can often be managed with patience, understanding, and targeted strategies. My journey with Luna and Artemis taught me the importance of addressing not just the symptoms but the root causes, whether they stem from stress, hunger, or the need for comfort. By adopting a compassionate and comprehensive approach, we can help our feline friends develop healthy, independent behaviors that will serve them well throughout their lives.
