My 3-week-old kitten isn't peeing or pooping. What should I do?

Updated on September 23rd, 2025

Pet's info: Cat | Domestic Longhair | Female | unspayed | 1lb

I found an orphan kitten on friday. She looks to be about 3 or 4 weeks old and she's been eating well. She was peeing with the help of stimulation but she would always go she's only pooped once. For the past two and a half days she has not peed or pooped there was a couple of times she went by her self but she seemed to just stop now. She's still running and playing. What should I do?

Now that she is 3-4 weeks old she may be peeing or pooping without your knowledge. Go ahead and start teaching her the litter box but make sure it is small enough that she can get in and out. If you haven't already I would also start weaning her to cat food. At first you will still have to supplement with formula but you start by putting all for feet in canned food on a paper plate. Soon she will start eating that. And once she gets a little older, approximately 6 week, you can start adding softened kibble. The fact that she is still playful and acting normally, I do not think she is block and not urinating or pooping. Usually they will become lethargic. If you still haven't see any irons or poop in the next day or she becomes lethargic then I would see your vet for an exam. They will be able to tell if she is constipated or if the bladder is really large. I hope this helps!

How often should a 3-week-old kitten poop? She hasn't gone in days.

3 weeks is very young. Under normal circumstances a kitten should be with its mommy until it is 10 to 12 weeks old. Your kitten will still need to be fed with kitten milk (bottle feeding). You can get a bottle and Kitten milk at a large supermarket or your vet;s office. At three weeks, the mother still licks and stimulates the kittens genitals and anus to entice it to urinate and defecate. She then removes the urine and feces. You will need to do this with a soft tissue moistened with warm water every time you feed her. At 3 weeks of age she should be fed every 4 hours. Once she is around 4 to 5 weeks old you can offer her canned kitten food in addition to the milk.

My 3-week-old kitten pees but won't poop in the litter box. Help!

It is possible that the kittens just need a little bit more time to figure out the litter box. Three weeks is still quite young and they may not fully understand what the litter boxes for. I would recommend enclosing both kittens in a small area with one to two litter boxes that are cleaned daily. In most situations kittens will figure this out relatively quickly. There is also a litter additive called Cat Attract that may be helpful in enticing Laila to use the litter box for pooping. I would also ensure that Laila is able to get in and out of the litter box provided with minimal difficulty. Using a litter box with low sides may be beneficial. If this continues to be a problem I would recommend consulting with your veterinarian as she may have an underlying medical condition such as parasites exacerbating this issue.

Why hasn't my 3-week-old kitten pooped in 2 days? Is she constipated?

MIracle is REALLY cute! You could check to see if she is dehydrated by pinching up the skin between her shoulder blades. If it is slow to go back to normal then she is dehydrated which could be contributing to the lack of feces. I would have your vet take a look at her if she is dehydrated so they can give her a little fluids if needed. If she is well hydrated then I would continue to feed her every 3 hours and be sure to use a warm wet cloth at every meal to rub around her anus. This will help to stimulate her bowel movements. If she still hasn't pooped within the next 24-36 hours then I would have your vet look at her. With her being so small, I don't want to give her a bunch of stuff over the counter as they can be quite sensitive. I hope this helps!

My 8-week-old kitten isn't pooping. Is this normal for a new kitten?

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! You should offer a small amount of food about 3-4 times daily and in really small kittens, every few hours might be needed. Eliminations and the frequency thereof, are dependent on many things depending on food intake, type of food, water intake etc. As long as she is not straining and trying to poop, it could be up to another 24-36 hours. She is getting accustomed to her new and that is probably slowing up the fecal elimination process. Again, no straining to have a bowel movement usually means that everything is ok, especially if the kitten is eating and drinking normally. Just keep monitoring for a bowel movement and monitor behavior, appetite, etc. If things change and you are unsure have your veterinarian evaluate the kitten. I hope everything works out ok.

How to get my new 5-week-old kitten to drink water and poop normally?

Hi there! Congrats on your kitten! If your kitty is eating soft kitten food on his own, he may be getting enough fluid from his food. I would keep offering water, but I wouldn't be too worried about how much he's taking in as long as he continues to grow and be playful with a good appetite. As long as water is available, he will figure it out. Canned kitten food is more complete and balanced than formula, so if he's eating that then it's a better option than formula. You could encourage a bit more water intake by adding extra water to his canned food and mixing it into a slurry. It wasn't indicated how long you've had him, so I'm not sure if the not pooping is a concern. Cats will generally defecate about 1-2 times daily. Of course, if you feel something isn't right, then it's best to have him checked out by your vet.

My 6-week kitten hasn't pooped since switching to wet food. Is this normal?

A 6 week old kitten should be able to be on normal food without milk right now. I would wait another day to see if she poops. Constipation isn't super common in kittens, especially on wet food, but it is possible. If Luna doesn't have a bowel movement by tomorrow, she should get checked out by the vet.

My 5-week-old kitten barely pees. Is this normal for kittens?

If she has a good appetite and is having normal BMs and is active, she is likely passing urine. It is probably a small amount each time it gets lost in the litter box or is missed with the BM so it is hard to tell the difference. I would confine her and make sure she is not using the bathroom outside of the litter box.
