Heard meowing at 8am and ignored it for about 2 hours. Then went

The mother probably abandoned it for a reason, but just realize taking care of a kitten is tough.
You gotta feed it every 3-4 hours and wipe it's bottom with a warm cloth after to get it to poop.

Can cats who recently had litters feed and take care of others' kittens?

Kitten meows when I try to leave it in a petbed so now I have it on my arm next to my body. It's relaxed and stopped meowing.

Unfortunately,I couldn't get a bottle and tried to feed it with a syringe but its a tad too big. Any suggestions or further things I should know until the morning?

Make the kitten pee. Kittens (and puppies) can't do it on their own until 3-4 weeks.

Get a hot water bottle and wrap it with a towel.

Also, it definitely isn't "big". It looks tiny and un-weaned.

Go to Walmart to get an empty syringe and powdered kitten formula (I lived in Opelika Alabama at one point at even that store hat kitten milk). Give once every 3 hours.

Take to a vet ASAP in the morning.

Yes, they have been known to adopt other kittens from time to time. It's not common but not unheard of either.

Does it happen less often than with dogs?

It's not uncommon, it happens a the time and it's highly encouraged. For feral cats, not so much because there's nothing stopping momma cats from moving kittens around(as queens do often in a 'wild' setting).

New dog and cat moms are very accepting of new babies, more so with cats. Their mom hormones are raging and it makes them docile and motherly to the point where vicious hunter cats most of the time won't even blink if you slip an entirely different species babies under her such as squirrels or rabbit kits.
