The difference is, if car drivers want to play silly buggers with a 40 ton artic, that's up to them.
These little buggers aren't meant to replace our real life furry friends, but if you are allergic to cats or dogs or just don't have the time to care for one then a cyber pet (also known as a virtual pet) may be your best solution.
Widespread use of DDT mostly eliminated the problem, but since DDT was outlawed, these buggers are back and infesting homes, hotels, and even theater seats.
Be sure to check your dog for ticks periodically, and if you live in an area known to have high tick traffic, take precautions to make your landscape inhospitable for the little buggers.
