Why won't my 6-week-old feral kitten eat? Should I get formula?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | unneutered | 1lb

2 days ago I found a feral kitten. He was aggressive at first (he is about 6 weeks I think I'm not sure) and ran super fast, but gained trust super fast and now runs up to me and purs when I let him. He ate normally and drank good on the first and second day, but now won't eat. He drinks water normally and acts normally and is litter trained already. He used to eat wet food and dry food now only drinks water. I force fed and got him to eat a little. Should I buy formula? He grooms himself too.

Hi, it looks like you're offering both canned and dry food which is great. Little kittens don't eat very much, so maybe he is just full. He may also have parasites like intestinal worms which make him feel full. If he doesnt eat tomorrow, you should take him in to a vet. Good for you for adopting him.

    Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Congrats on your new kitten! Combo is a great name! You can try supplementing some canned food or try a different dry food. I like Purina kitten chow. Make sure he has been dewormed and his vaccines are up to date. If he is growing and isn't too thin and isn't vomiting or having diarrhea he may be fine and just need time to adjust to his new home. I hope this helps and good luck!

Two small kittens were dumped off at our house. The tabby won’t eat wet mixed with kitten formula or take a nipple. He’ll eat a couple of pieces dry but won’t eat it softened. I have been using an eye dropper to get formula in him. He’s very active a
Good for you for taking in Lil' Homie and his brother! Looking at the picture, I'm roughly estimating that he's likely close to 6 weeks old. However, it's impossible for me to be more accurate in my guesstimate without knowing his body weight and checking out his teeth. With that in mind, by the time kittens are 6 weeks old, it's perfectly fine if they only eat solid food - including dry kibble. Some cats simply don't like wet food for one reason or another. If Lil' Homie is willing to eat dry food, continue to offer it plain several times per day. He should eat around 1/3 to 1/2 cup of dry food alone per day, but this volume changes a bit depending on the specific variety of food. You can also put some kitten formula in a bowl for him to drink, as well as continuing to offer canned kitten food. If he's eating a good bit of dry food, he won't also need the formula or canned food. If you're concerned that he isn't willing to eat enough of the dry food, you could also try adding a bit o

I’m feeding a six week old kitten moist food through a syringe, because it won’t eat, but will drink water out of bowl, how much do I feed her at a time and how many times a day.
At six weeks of age, it's time for Heavenly to start eating a kitten formulated food. Because she will drink water out of a bowl, she can eat food out of a bowl and you do not need to syringe feed her. I can give you a method to wean her onto dry food. To help her wean and to get used to dry food, I would soak a high quality kitten formulated dry food in warm water until soft. Then mix that with kitten formula such as KMR to make a mush the consistency of oatmeal. Over the next two weeks, gradually increase the amount of dry kitten food and decrease the amount of water and KMR you use until she is eating the dry kitten food only. Best of luck, I hope this helps!

I have adopted a kitten age of about 6 weeks. After moving to my house she is not eating much. what should I do? what vaccines needs her now?
I would recommend that you have the kitten examined by a vet if she isn't interested in eating food. You can try a variety of wet kitten foods, or mix dry kitten food with water or kitten milk replacer (not cow or other types of milk). At 6 weeks of age, she needs an FVRCP vaccine.

We have a orphaned kitten. It's about 4-6 weeks old. We're having trouble feeding it. It won't eat. We got a kitten bottle and milk replacement for it
If the kitten is 4-6 weeks it should be fed solid food, not milk. You should try kitten wet food, warm it up before offering to the kitten. If kitten allows, you can hand-feed or even syringe feed. Please, remember that kittens at that age should be fed very small amounts every 2-3 hrs.

Thank you for submitting your question regarding Shadow. What a cutie! He will need to eat a kitten formula of dry or canned food. It is normally wise to do a gradual diet change. However, it does not sound like he is eating the formula you have well. In this case, it will be fine to just offer him a kitten version. You can try adding warm water to the food. It may make it more appealing to him. If his appetite stays low, he will need to see a veterinarian to ensure there is not an illness present. I hope this information helps!

All the kittens in the litter have died but one, I'm worried it will happen to her too. I don't think the mother is producing milk. Baby won't take bottle, doesn't want it out of a bowl, doesn't want dry food, or water. She is about 5 weeks old. What
At 5 weeks Baby should be old enough to start eating some solid food. You can try mixing some canned kitten food with some kitten formula like KMR and putting it in a shallow dish. If she still won’t eat I would recommend seeing a veterinarian to determine what might be wrong. They can also teach you how to tube feed if necessary.

I have an abandoned newborn kitten that I think is about a week old. I don't know how much food she is supposed to have, but I'm worried she isn't getting enough. She is only eating about 1/4 oz. of kitten formula or homemade "kitten glop" every feed
How much she needs to eat depends on the kitten formula that you use. There will be instructions on the packaging for her daily needed amount based on her weight, and you divide that amount into how many times per day you feed her. I would recommend that she stay on solely kitten milk replacer until 4 weeks of age, when you can start to introduce her to kitten food mixed with milk replacer. If she doesn't eat the full amount that she should from a pet bottle, you can have a vet show you how to tube feed her. Her large belly may be full of food, but it could also be full of worms. I would recommend that you deworm her when she is 2 weeks old. Here is a good article on raising orphan kittens: http://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=576

I have a malnourished 8 week old kitten. He is to week to eat food so I am having to basically force feed him formula every 2 hours. How much should I feed him?
Hi there. An 8-week-old kitten should be eating regular solid food at this point, not formula. If he isn't eating on his own, you can get canned kitten food and mix it with a little bit of water to form a slurry, and then use an oral dosing syringe to gently put it in his mouth.

Thank you for contacting Boop by Petco with your question about Gaiman. Congrats on your new kitten! At six weeks of age, he will be fully weaned and does not need formula. Keep feeding him the wet kitten food, and you can start introducing small amounts of dry kitten for him as well. Give him the same brand of dry food as the wet food. He is not too young to be adopted out. I would consider six weeks the minimum age to be adopted out. I hope this helps!

My 8 week old kitten keeps crying for food. I feed it at 7am and 7pm but it starts to cry at about five pm. It wont eat his dry food and I even tried to warm it up. I also got it some kitten milk but he refuses to have it.
Small frequent meals are better for a kitten this young. Yuo can try other brands if he is refusing this cat food, but you can also try moistening it with a little water or low sodium chicken broth as well as warming it to see if some combination entices him to eat better for you. If you can, leave out dry food for him to nibble on all day long and give him a small amount of wet food in the morning and evening.
