2 kittens about 5 months

Hey guys. I'm visiting Bangkok and found two kittens in a box on the street. They looked abondoned and lost. After a visit to the vet, it seems one is male and the other female. The female one is pregnant but otherwise healthy. They are at my rented apartment now and I can tell that they are pets for sure. Initially a bit skittish but one of them is already purring in my lap. They're also using the litter box just fine.

I won't be staying in Thailand long and don't really know anyone here per say. I'm really hoping someone here will consider taking them in or maybe you know someone who would. Please help.
