Is it normal for my 5-year-old cat to suddenly grow taller?

Your cat's sudden growth spurt probably has less to do with the introduction of the male cat and more to do with the levels of growth hormone in her system. Feline growth hormone will be increased in cats around the age of maturity (2-4 years). Some diseases including diabetes melitus and acromegaly are also associated with higher levels of FGH. Finally, stress can also result in increased growth hormone levels. If the introduction of the male has caused Deesa to be extremely stressed, then it could be possible that the growth spurt is due to his introduction to the house.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! She could have a congenital issue like dwarfism or be a certain breed like a munchkin. There are genetic endocrine issues like hypothyroidism that can stunt growth but that is exceeding rare. It’s hard to say if it will affect her life span without knowing if her stunted growth is from a medical condition. Next time you take her to the Vet have them look in to it. I wish you the best!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! At over 1.5 years old it is normal to stop growing. Most cats have reached their skeletal size before 1 year of age. Genetics play in to how skeletally big an animal or person will be. Either Wilkie has some small relatives are he is just abnormally small from a mutation. There is nothing you can do and if he is healthy otherwise enjoy is cuteness and him looking forever young! Have a great day!

Sometimes kittens are born as dwarf and will not grow much. This is a rare congenital disorder. More often kittens that do not thrive or grow normally have a congenital heart defect or a liver shunt. I suggest you have Foxy examined by a vet to rule out the latter problems, as there will be healt implications for her future life. Here is some information on those conditions: https://www2.vet.cornell.edu/departments-centers-and-institutes/cornell-feline-health-center/health-information/feline-health-topics/portosystemic-shunt https://www2.vet.cornell.edu/departments-centers-and-institutes/cornell-feline-health-center/health-information/feline-health-topics/congenital-heart-disorders

If Silver is almost three years old now, she should be completely finished growing - so I would not expect her to get any bigger. Some cats do stay very petite in size; this isn't necessarily abnormal, as long as she seems healthy otherwise. If she is eating and drinking fine, active, and not overly skinny then I wouldn't worry - she may just be a small kitty :)

Cats stop growing by 11-12 months of age in general. It is likely Ella is done growing. Some cats are small but I recommend to have her examined by the veterinarian with some bloodwork to make sure everything is normal. I hope this helps and please feel free to post any additional questions.

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!
