How Big Do Tabby Cats Get? Average Size & Growth Chart

Tabby cats are commonly mistaken for being a specific cat breed. However, the word “tabby” refers to a cat’s coat pattern, and most cat breeds can have the tabby pattern. With that being said, tabby cats can grow to be different sizes. The best way to get an accurate estimate of your tabby cat’s growth is by determining their breed and following the breed’s growth and development rate.

What Affects a Tabby Cat’s Growth

Several other factors besides breed will affect your tabby cat’s growth. Genetics plays a strong role, and it’s common for tabby cats to grow to a size that is similar to their parents. Female tabby cats also tend to be smaller than male tabby cats.

Environmental factors also play an essential role in a kitten’s growth and development. Kittens have specific nutritional needs that are different from the nutrients an adult cat needs. If these nutritional needs aren’t met, kittens will face abnormal growth or become malnourished. Malnourished kittens tend to be smaller and are at risk of delayed growth and development and long-term health issues, including kidney disease, muscle weakness, and skin and coat issues.

Kittens must also engage in enough exercise every day. Exercise promotes the healthy development of muscles, bones, and joints. Healthy play also helps develop a cat’s eye-paw coordination, balance, and agility.

The Importance of Tracking Your Tabby Cat’s Growth

Tracking your tabby cat’s growth throughout the first year of their life can help immensely with ensuring your kitten is on a healthy growth and development track. Regularly measuring their weight will enable you to know if your kitten is underweight and needs more food or if they’re overweight and need to cut down on food portions.

Drastic changes or fluctuations in weight can also indicate underlying health issues. Keeping track of your kitten’s weight will enable you to record and notice these changes more quickly. This will significantly increase the chances of you getting your cat to your veterinarian as soon as possible for examination and treatment.

How to Track Your Tabby Cat’s Growth

You can easily track your tabby cat’s growth by using a pet scale and keeping all your records in a notebook. Since kittens often have difficulty sitting still, it’s often easier to weigh them if you enlist the help of another person. Another person can guide and keep your kitten on the scale while you record their weight.

Since kittens tend to grow rapidly during their first 6 months of life, it’s best to record their weight daily or every other day during this period. As their growth tapers, you can track their weight every few days or every week until they reach adulthood.
