The cats in the photos are mostly strays or street cats found in Singapore, also known as the "Lion City". They are also called community cats as they were trapped and spayed and now looked after by caregivers living in the neighborhood. Thank you for visiting.
PS: The cat was actually not stalking the pigeons... It was creeping over to the right side of the field to look at some crows on a tree (see pic below). Looked like it was trying not to scare the pigeons by "tiptoeing" past them :-)
