Why are my 5-week-old kittens not eating wet food or potty training?

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'm sorry to hear you're struggling with the kittens! At 4-weeks they should be starting to get a little interested in wet food, so continuing to try the slurry should help. You can put a little on a spoon or on their noses to see if they will lick it off to encourage them to try it. Keeping the formula warmed and feeding them on their stomachs (in the same position they'd be in when nursing from mom) may also help them recognize you are trying to feed them. If they're not on solid foods yet, they may not have a whole lot in the way of stool production, and any stool they produce may be very liquidy still. It's a good idea to bring them to the vet anyway, especially if orphaned, as they may need to start getting vaccinations sooner to account for the loss of mom's natural antibodies, and your vet can examine them, deworm them, and treat any issues as needed.

Warm the food slightly or mix n a teaspoon of baby food to stimulate his appetite. A gruel or slurry can also be made using dry kitten food and an appropriate kitten milk replacer. Do not use cow milk. Gradually decrease the liquid and mix in wetr food. Then, you can gradually decrease the dry food until he is eating canned food only. Patience and consistency are necessary in litterbox training. When he defecates or urinates outside the box, use a tissue to pick up the stool or soak up the urine and transfer it to the box. Place him in the box to sniff and inspect it. Litterbox attractants may also help to get him into the box.

If the kitten is only 15 days old it should be on a completely liquid diet of formula (KMR or another kitten replacer) as it is way too young to be eating any solid food. Once the kitten is about a month old you can start to introduce solid foods such as wet kitten food mixed with a slurry of the formula and then start weaning to more solid foods from there. The kitten likely also doesn't know how to properly use the bathroom yet, so using a warm washcloth on its bottom can help stimulate it to go much like a mother cat would do. Once it is a bit older you can start bringing it to a litter box as well.

I am a fan of Royal Canin, so yes I would recommend switching your new kittens to all Royal Canin. It's a very high quality food, and because they have veterinary nutritionists on staff, you are assured the food is balanced to meet your kittens's nutritional needs. I would feed them according to the instructions on the bag. It could be one of your kittens has intestinal worms, causing its stool to be a little wet. These are common in kittens. Make sure both your kittens are up to date on their deworming treatments. I hope this helps, and enjoy your new kittens!

St four weeks old she might be ready for solids. You could mix some canned kitten food with milk replacer and put it on a flat plate to see if she'll eat it. If not you may need to talk to your veterinarian about bottle feeding or tube feeding. I would recommend keeping a very shallow litterbox close by and putting her in it periodically. Depending on how severely affected she is she may need some additional help, and your vet might be able to give some other pointers.

At the age of 6-7 weeks, these kittens are completely capable of eating dry kitten food. Perhaps this would help to regulate the stools and firm them up. You can do a combination of soft kitten food and the dry kibble.
