The YiShan Stray Cat Base (易善流浪猫基地) is collection of four separate feeders found on the Hello Street Cat app. They're located in the "cat" area of an animal sanctuary, and are being managed by the respective “YiShan Animal Protection Society" (易善爱护动物协会), of which is similar to Team BingBing from the Team BingBing Helps Stray Cats Find Their Forever Home feeders, where they catch and neuter animals before adopting them out to interested pet owners.
As there are 4 different feeders in the shelter, different cats tend to visit different feeders, although some can be seen at multiple feeders.
YiShan cats are notable for having particularly interesting breeds, including Scottish Fold and Sphynx. Some cats may become unseeable due to adoption.
