4" ducting, 120 CFM fan vented to the outside with a standard 4" dryer vent, cycles fresh air into the boxes all the time. The boxes get cleaned weekly but you never get the "OMG Cat, wtf did you eat!?!?!?!!" moments when they take a dump. It also makes cleaning the boxes more plesent. The clumping cat litter works much better this way. Cats are healthy, happy and don't mind the fan noise..
Dutch artist Bart Jansen was rather heartbroken when his cat, Orville, was hit and killed by a car. However, Jansen decided to memorialize his deceased buddy in a unique way: by turning him into a helicopter.
Yup. A helicopter. Jansen is quoted as saying:
"Now he is finally flying with the birds. The greatest goal a cat could ever reach!"
False. If his body turned into a poptart and he began flying around the sky with a rainbow trailing him, THEN he would reach the greatest goal a cat could ever reach!
