Not on a general basis (it's water) but kittens are noted for worms (common) and you should see your vet and if possible take a stool sample from your kitten to the vets on the same day you are seeing the vet.
I wouldn't recommend it - you don't know the cause of the wet stools in the rat. It could have an infection which may cause the snake problems if it ate it.
I am sure I could feed my kitten wet food because wet food can help with hairballs and can be a good source of water especially because most cats don't drink a lot of water. My kitten is a Maine coon and has a ton of fur so wet food can help him digest hairballs.
If your kitten only eats wet food, it is important to ensure they are getting a balanced diet. You can try offering a variety of wet food flavors and textures to see if there is a preference. It is also recommended to consult with a veterinarian to ensure your kitten is receiving all the necessary nutrients for their growth and development.
Take it to a vet?
You cannot leave wet food out for longer than half an hour, as it will begin to dry up in the air and become rancid. A kitten will not starve if left without food during the night, although you could put a small amount of dry food to leave overnight if your kitten seems particularly hungry.
In an emergency, you can feed a kitten a mixture of canned or wet cat food and kitten milk replacer to ensure its health and well-being. It is important to consult a veterinarian for specific guidance on feeding a kitten in an emergency situation.
Try feeding it some cooked plain chicken or white fish until the kitten's stools have firmed up. These are very bland foods that are very gentle on an upset stomach. As diarrhoea can quickly dehydrate a kitten, it is highly advisable to get some liquid into your kitten (kitten milk, water with a little broth in or mix water with the food), and to take your cat to the vet. A kitten (especially a very young one) with diarrhea can get very dehydrated very quickly and that can easily become fatal.
