Snakes do have bodies as well as tails, it’s just not very apparent. The “body” part is comparatively long, while the tail is quite short. Cephalopods, however, are literally named “head-feet”.

They do have mosquitos.

Also be prepared to let the walk take 5 minutes or less if the cat doesn’t feel like it. Or if they find it too scary (but might want to try again a little while later).

What is the halo made of? Dust?

In my opinion, that’s just another benefit.

My cat is less scared of the robot vacuum than regular vacuums. Possibly because it is small and moves in a predictable pattern?
