As detailed in a recent paper in the Journal of Feline Medicine and Surgery, the research facility was created by University of Illinois researchers in order to study a new type of feline contraceptive that could drastically reduce feral cat populations. Although spaying and neutering cats is an effective way to control feline populations, the minor surgeries are expensive and invasive. An injectable contraceptive vaccine called GonaCon showed promise as an alternative population control mechanism in a variety of mammals, including laboratory-raised cats, but testing its effectiveness in the wild proved difficult.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
