Shelter-culture in Colombo isn’t like it is in the West. That said, there are shelters run by very passionate people who go to great lengths to save and protect cats and dogs. If you wish to adopt a street dog, then Embark hosts an adoption day on the last Sunday of every month. Tayo Bear has also introduced this idea. This is also a good chance to network and meet with other people who run shelters. They often have cats too. It is worth advertising on the Facebook expat groups, people often have animals that need adopting.
