Dr. Solano is an excellent vet here in Atenas. His telephone numbers are 2446-6646 and 2446-6068. He also has a cell phone: 8995-8585 and email: email@example.com. His office is located 100 meters east of the ICE office (ICE being the acryonm for Instituto Costarricense de Electricidad - the Costa Rican government run electricity and telecommunications services provider).
Cat (the name that has stuck) was very unhappy in the carrier and the short taxi ride but was a good boy while being examined by Dr. Solano and his assistants. This is a cat that is outside all day, hunting and lolling around in the grass/dirt so he had fleas and no doubt worms. He stays inside at night. He needs to lose some weight so we have him on a calorie reduced diet now. Dr. Solano said Cat is built larger then most Costa Rica cats.
The treatment Cat received was: deworming, flea treatment (Frontline Plus, I think, or similar), Felocell and Leukocell shots, and feces exam. The total cost, including the consultation, was 48,050 colones - about 96.00 USD. We also bought 1.5 kg of weight reduction kibble for 9850 colones (19.00 USD) and a product to spray on furniture to kill any fleas. Pet food in Costa Rica is pricy because it is imported.
Here is the dewormed and flealess version of Cat:
