Cats' Winter Urinary Blockage: Reasons & Prevention

Reasons for Feline Urinary Blockage in Male Cats:

1. Genetic Influence

Most of the cats we encounter trace their ancestry back to desert regions, where a dislike for drinking water has been ingrained in their genes. This genetic predisposition not only leads to reduced water intake but also a lack of welldeveloped sweat glands, resulting in minimal perspiration. Consequently, the kidneys must recycle and absorb water multiple times to maintain body balance. This is why feline urine often has a strong odor. As urine is repeatedly concentrated and reabsorbed, it can crystallize, forming small crystals that are typically excreted with urine. However, due to the infrequent urination in cats, these crystals can accumulate and form stones within the urinary tract, leading to urinary blockage and the condition known as urinary retention.

2. Anatomical Differences

The primary difference between male and female cats lies in their anatomical structure. Male cats have a narrow and long urethra, whereas females have a wider and shorter one. This makes male cats more susceptible to urinary blockage when they have bladder stones or inflammation, as the narrow urethra can become obstructed. Additionally, male cats that are not neutered may experience irregular estrus, increasing the risk of urinary tract infections. Unneutered male cats typically start their first estrus around 68 months of age, unlike females who have several estrus cycles per year. The unpredictable nature of male estrus can lead to bacterial backflow during genital rubbing, potentially causing urethritis. While female cats are also at risk of urethritis, the likelihood of urinary retention is relatively lower.

3. Seasonal Influence

Cats are more prone to urinary system diseases during winter, as lower temperatures create an ideal environment for bacterial and viral growth. Moreover, cats tend to drink less water in the cold season, further increasing the risk of urinary tract infections.

When a cat experiences urinary retention, symptoms may include frequent urination, pain or crying during urination, and an increased frequency of bathroom visits. In severe cases, the cat may be unable to urinate at all, leading to a full bladder, decreased appetite, listlessness, and a decrease in activity levels. If left untreated, this can be lifethreatening for the cat. Therefore, it is crucial to take immediate action if you notice signs of urinary retention in your feline companion. Don't hesitate to consult an online veterinarian for guidance and advice.
