Hi, Laura, I don’t think you’re unreasonable to be a bit worried. There could be more than one reason for Polly’s diarrhea, eg worms, bacterial infection, but diarrhea can become life-threatening to young kittens because of dehydration, whatever the reason, and most especially if they stop eating and drinking. So I really would suggest a visit to the vet. You might as well take both of them at the same time for a general check-up, it won’t be wasted, as soon you will need to plan with the vet about their shots and if they need worming, etc. I don’t know if you can get something called Scourban where you are, that can help.
I would also suggest a paste called Nutrical for kittens, it is great for supplementing the feed of under-nourished or sick kittens. It has everything they need in it to build them up.
And, finally, I know our kitten expert, Buttons, would suggest goats milk (canned in the baking aisle at Walmart) or, even better, goats milk yoghurt (from a health store) to help replenish the helpful flora in Polly’s tummy. Fortiflora can also help.
The main thing is to keep an eye on Polly for dehydration, which can set in very quickly in young kittens. I’ll give you the tent test and recipe for homemade pedialyte:
The tent test is to test for dehydration:
Tent test: pick up a good pinch of kitten’s skin at the neck and let go.If it snaps back immediately, she’s hydrated okay. If it takes a little time to go back down, or, worse, it stays up in a ‘tent’ shape, she needs fluids, such as pedialyte (from the supermarket, children’s aisle) or home-made pedialyte below.
Note, in the United Kingdom, pedialyte is called Dioralyte. Also known as rehydration salts.
Home-made pedialyte (from World Health Organization)…no preservatives so short life-span
* 1 cup water (boiled then cooled)
* 2 tsp sugar
* 1/8 tsp salt
* 1/8 tsp baking soda
* (this Pedialyte formula gives needed electrolytes & some sugar for energy)
Combine all ingredients and warm slightly.
Make new after 24 hours.
The constant miawing suggests to me that she’s either hugely hungry because of the diarrhea or something’s causing her distress. So I think the vet really is a good idea. Also click on the pink tag ‘diarrhea’ for other threads on this subject. Best of luck, they sound adorable!
