Well, it turns out that just like humans, cats also come in different shapes and sizes. And one factor that plays a big role in a cat’s size is its breed! Some cat breeds are naturally smaller compared to other cats.

2. The Genetics Could Play a Role

If you’re having the feelings: “my tabby cat is so small” or “my cat still looks like a kitten” it could be because of its genetic makeup.

If its parents were smaller in size, your cat likely inherited those genes, resulting in a smaller size! Genetics can play a big role in determining their size!

For instance, a mother cat is small in size and has genes that code for a petite frame. If the father cat also has similar genes, there’s a high chance that their offspring will inherit those genes as well!

3. Your Feline Friend’s Health!

A cat’s early development is crucial for its growth and development. Health issues during this time, such as poor nutrition or illness, can significantly affect its growth and result in a smaller size.

Poor nutrition can cause a lack of essential nutrients, such as proteins, vitamins, and minerals, crucial for a cat’s growth and development. Without these nutrients, a cat’s growth can be stunted, resulting in a smaller size than expected.

For example, if a kitten doesn’t receive enough protein during its growth stage, it may have weaker bones and muscles, leading to a smaller size and weaker physical abilities.

But with the right care and attention, you can ensure your cat achieves its full potential and healty size.

4. Age Also Matters!

Age plays a significant role in a cat’s size. If you’re having worries like “my cat is small for her age,” it’s possible that it may simply be in the process of growing and may reach a larger size as it matures.

Here is an overview of a cat’s life stage by months, along with the typical sizes for each stage:

Life Stage

Age in Months

Size

Neonatal

0-4

3.5-5.3 inches, 3.5-5.3 ounces

Transitional

2-4

4-6 inches, 8-14 ounces

Socialization

2-7

6-10 inches, 1-4 pounds

Juvenile

7-12

8-10 inches, 3-6 pounds

Adolescent

6-18

9-12 inches, 5-9 pounds

Young Adult

6-18

9-12 inches, 5-9 pounds

Adult

1+ year

9-10 inches, 5-10 pounds (depending on breed)

Senior

7+ years

9-10 inches, 4-8 pounds (depending on breed)

At 6 months, cats are typically in the latter half of their juvenile stage and are starting to reach their adult size, while at 8 months and 9 months, cats enter their adolescent stage and may experience a surge of energy and changes in behavior.

Cats generally reach their full size and weight by around after a year up to at 2 years of age, and factors such as breed, genetics, and overall health can still play a role in determining their size.

Appropriate care and attention throughout each life stage are important for a cat’s overall health and happiness. And try not to worry too much if your little fur ball seems petite right now—they may have some growing left to do!

5. The Environment and Diet Are Also Factors

Did you know that the environment in which your cat lives can also impact why it could be small and skinny? The diet and exercise level of your furry friend are important factors that can affect its growth.

If your cat has limited access to food or lack opportunities for physical activity, it may not reach its full potential size.

So, make sure your cat has a balanced and nutritious diet and plenty of opportunities for playtime and exercise. This will help your feline friend grow to its full potential size and lead a healthy and happy life.

6. Other Factors
