How to tell a new kitten's age, gender, and what food it needs?

The general rule of thumb is about 1 month of age for each pound of weight. This is not accurate in all cases though. Baby teeth, incisors and canines (fangs), erupt at about 3-4 weeks of age. If Lucy has all her baby teeth, she is at least 6 weeks old. You should be able to determine sex right away. This is how: Lift the tail. Right under the tail is the anus. Below that is another opening which is round in males and a vertical slit in females. Also, the distance between the anus and genital opening is greater in males. A physical exam by your vet can confirm gender. You can also post a clear picture of the back end in a new question and we can let you know.

What a cutie! Determining a kittens age can sometimes be narrowed down by the appearance of the baby teeth and then the adult teeth, as well as the kitten's size.

I would bring her to a vet as soon as possible as it is very common for these guys to have intestinal parasites (bring a stool sample with you) and she may be old enough to start her vaccines to protect her from illness.

From this photo, this appears to be a male kitten. You can read more about determining kitten gender at https://www.vetmed.wsu.edu/outreach/Pet-Health-Topics/categories/procedures/cats/determining-gender-(sex)-of-a-kitten

So cute! You can age young kittens by weight. They should weigh about a pound per month when young. The best food is KMR (kitten milk replacer). I have also attached an extensive link that may help you with the kitten process.

Thank you for submitting your question regarding your kitten. It is difficult to say age just from a picture, but I guess she is around 6 weeks of age. Her baby teeth have erupted, but she appears quite small. Kittens typically weigh 2lbs at 8 weeks of age so you can use this as an estimate as well. I hope this information helps!

Most cats can be fixed once they are over a certain weight rather than a certain age. Bringing him to your vet to be weighed and talking with your vet can let you know if he is large enough to be neutered. Your vet can also check for any remaining baby teeth in his mouth, as well as adult teeth that have come in to give you a closer estimate of his age. (It's hard to tell from your photo if those are still baby teeth or if they are adult teeth coming in, but this usually happens starting around 3-4 months of age, and finishes around 6-7 months.)

It's hard to say for certain from the pictures, but I think this kitty may be a girl. At a couple months old, you should be able to feel testicles within the scrotum which is under the slit for a penis/vulva. If you can't gently feel testicles, then it's most likely a female, or possibly a male whose testicles did not descend.
