It costs 1400/-per cat for sterilization. NGO is run by Susmita Lahiri. To be booked appointment by calling her. It may take long time depends on number of surgery. 1st come and 1st service. Operation done by experienced doctor. Time takes for operation for one cat is 15 to 20 mins. Post operative care can be provided by the NGO. You need to talk to her. Overall location, cost, doc wise very good place to operate. Only one thing required to improve is its operation area.
