Abandoned newborn kittens: How to feed, warm, and manage diarrhea?
Hello. Use a cardboard box as a nest box. Put in a towel, & then a disposable diaper to absorb liquids. Change as needed. Put a heating pad under 1/2 of the box, so the kittens can move as they need more or less warmth.
Feed a Kitten Milk Replacer, either a premade liquid or a powder you mix as needed. If you cannot find a kitten milk, this is a formula you can try:
1/2 cup whole milk
1 egg yolk
1 drop multivitamins ( pet or children's )
3 crushed Tums ( or calcium based antacid )
Feed every 2-3 hours during the day, but do not wake them to feed them. They should do OK all night.
If diarrhea persists, you can temporarily add more water to the diet to meet fluid needs. Consider taking a stool sample to your veterinarian for parasite analysis. At 3-4 weeks, start to introduce a solid, soft diet.
Good luck & thanks for rescuing the kittens. Thanks for contacting Petco Pet Education Center, formerly Petcoach.
