Look we all worry about our pets while we’re at work, but 900 bucks on a robotic toy/webcam kit is a little steep. I spend at least that much on cat food and litter in a month to take care of my 50 cats. Luckily there is a cheap DIY way to keep track of your kitties while you’re at work. The Kitty Twitty Cat Toy will tweet every time your cat plays with it, letting you know that (for the time being at least) they’re not clawing up your furniture or spraying the rug. Follow the tutorial by Marc de Vinck to make your own or modify the design to create a tweeting dog toy, bird perch or burglar alarm.
