Should I be concerned about my 16-week Maine Coon kitten's 6lb weight?

Wow....he is totally adorable!!! He is larger than the average 6 month old kitten. At this age, the average kitten is usually 4-6 pounds. He does appear to have a long body and also some longer hair. These are characteristics of Maine Coone. It is certainly possible that he has Maine Coone genes...or he is just a very big domestic cat. Your vet may be able to tell you more once he reaches his adult maximum size. Thank you for using Petco Pet Education Center, formerly Petcoach.

Hi! Mars is super cute! As I am sure you are aware Maine Coon's are in general large cats. With that said, large does not equate overweight. It's difficult to assess ideal body condition from simply looking, you will need to put your hands on Mars. Ideally, what you want is to be able to see a bit of a wait taper behind his rib cage. You want to be able feel his ribs through a layer of fat. You shouldn't be able to count the ribs and they should also not be buried under so many layers of fat that you cannot feel them at all. Below I have included a link to The Ohio State Veterinary School's webpage with lots of great information on body condition and nutrition. I have personally worked with their board-certified nutritionist who is phenomenal, so the information provided here can't get much better. Hope this information helps you an Mars! https://vet.osu.edu/vmc/companion/our-services/nutrition-support-service/body-condition-muscle-condition-score-charts

Hi there and thanks for posting on Petco Pet Education Center, formerly Petcoach! Voldy is around 3lbs which is not completely out of the ordinary for a 4 month kitten. From the pictures alone, he appears well muscled and does not appear to be underweight (although a physical exam would be better at determining this). Kittens should weigh about 5 pounds at 6 months old, so I would continue feeding him a kitten food from Royal Canin and make sure he gets a kitten vitamin daily to encourage healthy growth. If you notice Voldy is not gaining any more weight or is eating less, you may want to have him seen by his veterinarian for exam just to make sure there are no underlying medical issues. I hope this helps!

Since Maine Coon cats can have a genetic disposition for a heart condition called HCM, I would take Count to a veterinarian for an exam and possible referral to a cardiologist. HCM or another heritable disease can inhibit growth.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! I would deworm him. Intestinal parasites are almost always present in young animals as they are passed from the milk. He could be getting more lean but this could also be an early warning sign that something is going on. I would collect a stool sample and have him seen for his first vet visit. The Vet can do an exam, test his stool, feline leukemia and FIV test him and consider giving his first vaccination. I wish you and Noah the very best!

Hello. As long as Sock is eating a good quality, name brand kitten food, then he will develop normally. He is a teenager now, & he will stay lean probably for the first year or so of his life. As he transitions into maturity, he will naturally begin to gain additional weight. Watch this, because Maine Coons do have a tendency toward obesity. So keep him on a kitten formula for the first 12-15 months, then transition him to an adult maintenance food. Take care.

A purebred Maine coon should eat kitten food until they are 15 months old so Goliath should probably eat kitten food till he is about 12 or 13 months old. Since he is a mix, he is not likely to get as big or grow as much as a purebred Maine coon. When he is a year old, have him examined by his veterinarian who may be able to get a good idea of how much more growth you should expect from him or if he appears to be done growing. I hope this helps and please feel free to post any additional questions.
