Why is my cat obsessed with the sink?

As cat owners, we often find ourselves scratching our heads in confusion over our feline friends’ peculiar behaviors. One such behavior that many cat owners have noticed is their cat’s obsession with the sink. You may have caught your furry companion perched on the edge of the bathroom sink, fixated on the running water or even curled up inside the basin. But why do cats exhibit this strange fascination with sinks? In this article, we will delve into the reasons behind this behavior and shed some light on your cat’s peculiar obsession.

What makes cats so drawn to sinks?

Cats are naturally curious creatures, and their inquisitive nature often leads them to explore new and interesting environments. The sink, with its shiny surface and flowing water, presents an irresistible attraction for cats. There are several factors that contribute to this obsession:

  • 1. The allure of running water: Cats are instinctively drawn to running water. In the wild, they would seek out flowing streams for hydration. The sight and sound of running water in the sink mimic this natural instinct, making it an enticing prospect for your cat.
  • 2. Temperature preference: Cats are known to seek out warm spots for comfort. The porcelain surface of a sink retains heat, providing a cozy spot for your cat to lounge in.
  • 3. Elevated view: Cats are notorious for their love of heights and perching in elevated positions. The edge of the sink gives them a vantage point to observe their surroundings, satisfying their need for a high vantage point.
  • 4. Curiosity: Cats are naturally curious creatures, and they are intrigued by any new and unfamiliar objects or spaces. The sink, with its unique shape and texture, presents an exciting opportunity for exploration.
  • 5. Playtime possibilities: The sink offers a confined space that can double as a play area for your cat. They may swat at the flowing water or bat at objects placed in the sink, turning it into an impromptu playground.

How to encourage or discourage your cat’s sink obsession

If you find your cat’s obsession with the sink endearing and harmless, there’s no harm in allowing them to indulge in their fascination. However, if their behavior becomes disruptive or poses a risk, it may be necessary to redirect their attention elsewhere. Here are some tips to encourage or discourage your cat’s sink obsession:

  • 1. Provide alternative water sources: If your cat is fixated on the running water in the sink, consider providing them with a pet water fountain. These fountains mimic the sound and movement of running water, providing a similar experience for your cat.
  • 2. Create a cozy spot: If your cat enjoys lounging in the sink, provide them with alternative cozy spots where they can relax. This can be a cat bed, a heated blanket, or a designated cat perch.
  • 3. Distract with toys: Engage your cat in interactive play sessions using toys to redirect their attention away from the sink. This will help fulfill their need for stimulation and play.
  • 4. Block access to the sink: If your cat’s sink obsession becomes problematic, consider using barriers or deterrents to prevent them from accessing the sink area. This can be as simple as closing the bathroom door or placing a physical barrier in front of the sink.
  • 5. Offer alternative exploration opportunities: Cats are curious by nature, so providing them with other avenues for exploration can help divert their attention from the sink. Set up a cat tree, install shelves, or create a play area with tunnels and hiding spots.
  • 6. Reinforce positive behaviors: When your cat shows interest in something other than the sink, such as their designated play area or scratching post, reward them with praise, treats, or playtime. This positive reinforcement will encourage them to engage in preferred behaviors.
  • 7. Consult a veterinarian: If your cat’s obsession with the sink persists or escalates to the point of concern, it’s always a good idea to consult with a veterinarian. They can provide further guidance and rule out any underlying health issues that may be contributing to the behavior.


The sink may seem like an odd fixation for our feline friends, but there are logical reasons behind their obsession. From the allure of running water to the cozy warmth of the porcelain surface, cats find sinks to be fascinating and captivating. As responsible cat owners, it’s important to strike a balance between allowing our cats to explore their curiosities and redirecting their attention when necessary. By understanding the underlying reasons for their sink obsession and implementing appropriate strategies, we can ensure our cats remain happy, engaged, and content.
