A collar for wearing by a cat and for warning a bird of the presence of the cat that includes a strap for wearing around the neck of the cat, and an electric device disposed on the strap. An electronic circuit of the electric device includes first, second, third, and fourth pairs of dip switches, a speaker, a volume control in electrical communication with the speaker, a frequency generator in electrical communication with the volume control through an electronic switch and the first pair of dip switches. The first pair of dip switches adjust the frequency of the carrier wave generated by the frequency generator. The electronic circuit further includes a microprocessor that processes input from the second, third, and fourth pairs of dip switches and is in electrical communication with the electronic switch, and the second, third, and fourth pairs of dip switches. The electronic circuit further includes a light level detector in electrical communication with the microprocessor through a light detector switch. The electronic circuit further includes a power supply in electrical communication with the microprocessor through a power switch.
