He weights 3.95 kg ( 4.3 pounds ). He looks pretty thin to me. How can I know if it's normal and enough?

Have DoReMi examined by your veterinarian. Submit a stool sample to diagnose intestinal parasites which can affect weight and weight gain. Blood work may diagnose metabolic conditions or endocrine imbalances as well. Your vet can teach you how to assess your cat's Body Condition Score (BCS). This, in addition to weighing, can help you get and keep your cat into peak condition.
You can follow this link to familiarize yourself with the BCS prior to the visit to your veterinarian.

There are several markers (hips, ribs, waistline) that you look at to come up with DoReMi's body condition score (BCS). This is the best way to know if he is underweight or not. However since he is a kitten still, his appearance can fluctuate quite a bit as he continues to grow. Here is a website link that shows you just how to do this. Scroll to the bottom for the chart on cats. http://www.pet-slimmers.com/pet-obesity/how-to-tell-if-your-pet-is-overweight.aspx
But generally speaking, kittens that have weight issues almost always have concurrent vomiting, lack of appetite or diarrhea. If you still have concerns about his weight, then have him examined by your vet for an overall heath check-up to make sure that everything looks ok.

Your kitty is slim but not underweight. I think he looks perfect. Here is a body condition score chart where you can compare the figure of your cat.

Why is my cat so thin and how can I help him gain healthy weight?

Cats can be thin for a variety of reasons. Make sure he has been checked for parasites or dewormed recently. Some cats will also become thin due to kidney disease or hyperthyroidism. Sometimes this can happen even before kidney disease begins. Any GI disease will also cause a thin body. Lastly, some cats have a fast metabolism. Make sure Choo Choo's bloodwork is all normal and that parasites are not a concern. Then you may try focusing on nutrition. I recommend the brand Royal Canin. It's diets are all tested and formulated to contain appropriate protein levels that are high quality and easy to digest. Feed one of the higher calorie diets available. This may help to put weight on him. You can also supplement with a high calorie canned like A/D or R/S.

Is my Siamese cat too thin? How to know if he's underweight?

Hi, thanks for using Petcoach! Cats and dogs can vary in size based on genetics. If Kenny is small but otherwise healthy he is likely normal. If he is skinny then I would be sure he has been properly dewormed. It would be best to have his stool tested. If he is older then a physical exam and blood work may be warranted. You can always post a picture. I have attached a body condition score chart attached for you to view and decide if Kenny is too thin. I hope this helps and I wish you and Kenny the best! https://oregonvma.org/files/Purina-Cat-Condition-Chart.pdf

My adopted cat seems hungry and thin. Am I feeding him enough?

You can get a human scale and weigh yourself and then weigh yourself again holding him. Then subtract the two weights and you will get an estimate of his weight. I can tell you, it is VERY rare for a cat to be too thin. You would have to be severely underfeeding him. The biggest issue with pet cats is obesity so I honestly would not be that worried. If you get his weight once a month (as explained above) and you notice he is losing weight then you should get him to a vet for an exam.

My 4kg cat looks slim. Is that a healthy weight, or is he too skinny?

Hello! Felix is quite a handsome boy. From the picture, he doesn't look too slim to me, but I can't say for certain without seeing him in person. He should have a waistline, which it appears he does, and you don't want a fat cat. It's not healthy for him. My best guess from the picture is that he looks really good, nothing to be concerned about, but because I can't say it for certain, you can always have him checked out by a vet to be safe. I will also give you a link to a website that details body condition score in cats. This will help you determine if he's too skinny or not. I hope this helps :-) https://www.wsava.org/sites/default/files/Body%20condition%20score%20chart%20cats.pdf

How to tell if my cat is a healthy weight without a scale at home?

He looks a bit skinny, but it is difficult to determine from an image alone. An adult indoor cat should weigh between 8 and 10 pounds. It should have a layer of fat over the ribs, but you should be able to easily feel them. The hips should not be too prominent or "bony" and he should have a waist when looked at from above. You should bring him to your veterinary clinic to weigh him. They should allow you to do this for free. You could also buy. A small scale. Most are less than $30. Place him in a carrier or basket and weigh him, then weigh the container andbsubstract it from the total weight.

My cat looks skinny but the vet says he's healthy. Should I worry?

I would first want to rule-out a disease, or parasite causing him to lose or not gain weight. If the vet was not concerned about a possible medical issue, then I would not be overly concerned about her being a little skinny. The truth is that a score of four is not bad and lean cats are statistically healthier and live longer than overweight cats. Some cats (much like people) are able to naturally maintain a lean body condition. I suspect Choo Choo is one of those cats, but would urge you to discuss this with your vet before making any changes to his diet. At this time, I recommend feeding him normally and would not recommend a diet change until advised by your veterinarian. I hope that helps and all is well with Choo Choo.
