Welcome to TCS! & bless you for rescuing that cutie - wow, what a "paint job", s/he looks like a kitten from the "Chessie" series
Since the eye doesn't have any apparent discharge, it could be an irritation as well as an infection - my vet recommends washing with regular eye wash or artificial tears (not the kind for allergies). A vet check doesn't hurt, either, unless the little one is too stressed from the car ride. If the eye starts getting discharge, especially if it is yellowish, then it's a good idea to think "infection" and ask the vet for some antibiotic eye drops or ointment, preferably not with sulfas, which sting and teach a cat to run from treatment.
I also highly recommend a visit to www.kitten-rescue.com, created by TCS' very own Hissy (MA)! Excellent advice on that website. Also, I don't know if this applies, but if the kitten will still take a bottle or seems inclined to nurse, I do give "snack bottles", to prevent "wool-sucking" later in life. Most kittens, IMO, prefer the Four Paws brand because they take the rubber nipple better than the plastic ones on the PetAg brand. Same for baby bunnies
Please keep us updated & I'm looking forward to seeing you in the forums! Susan
Thank you! I was feeding with a syringe because he would take the bottle. But now he is eating out of a little bowl, I also give kitten food. No discharge so that's good. I might take him to the vet cause he hasn't had a bm in 2 days!!! I try to give him water but he really doesn't drink much. I will update.
He's very cute! I would not delay in taking him to the vet. He may need an antibiotic ointment. It's not normal for an eye to start to close and you don't want to wait for it to get worse.
You can add a bit of olive oil to his food to help with the poop.
How much and how often are you feeding? What are you feeding? Does he use the litter box on his own?
He should also have kitten kibble down all the time. If you can do the wet or milk feedings every 4 hours, that timing sounds about right. 6 hours is long for a baby this tiny. You can stretch it longer if there is kibble down though.
