Guidance required on veterinary services

I reside in Mumbai & checking to see whether the veternary services available are restricted to dogs or cats or does it cater to other animals? The reason I ask is because we found a nest in our house which was what we presume either infant Squirrel or Rat (unsure about what it was) it was so tiny the eyes also have not opened up but it was making sounds & moving hence we could identify it's existence. At that time we could not think of anything since we believe the squirrel must have laid this & never returned as there was no source to climb back in the gallery to where the nest was. We cdnt take risk of keeping it (at the time was unsure of exactly what it is) and we kept it downstairs in our building temporarily. I am not sure how do we go about it since I haven't really dealt with something of this sort earlier in my life. We wanted to save the baby however with mother not returning back we dont find a way to do that. What do you suggest in this case assuming the babies are fine?
