A small animal veterinary incubator is disclosed with an animal holding drawer that can be inserted into a temperature controlled enclosure and removed when not in use for cleaning and disinfecting. In various embodiments the incubator is portable, is at least partly transparent, controls interior oxygen and/or humidity, can use a hose to bring oxygen into close proximity with incubated animals, can introduce water-nebulized air or oxygen into the drawer through a hole, and can include a holder for a humidity bottle that humidifies air or oxygen supplied to the incubator. Some embodiments use an adjustable or regulated lamp to warm the incubator using an infrared bulb of 50 or 75 Watts. Temperature, humidity, and/or oxygen gages or sensors can be included, and the temperature, oxygen, and/or humidity can be automatically regulated. Preferred embodiments include closable vents that can be opened to allow for ventilation when only temperature is controlled.
