I was trying to visit the SPCA clinic last night because of a situation with Cissy, and realized that their opening hours are not really worker-friendly.
The time table they set is basically asking people to take time off to take their animal friends to see a vet there, otherwise, these people will be penalized to pay the emergency consultation fees. This time table is also punishing the animals they say they love, when their human companions could not take time off and could not afford the emergency consultation fee.
