I recently bought one of those vacuum robots that wander around the house to clean it.
I set it to clean the flat twice a day (it takes ~1 hour to clean the whole flat), and I'm having a problem with my cats.
I have an european/domestic cat and a Maine Coon (both approx 3 years old), male and one female.
The first time I turned on the vacuum, the european followed it a bit scared around all the flat and after few hours it stopped caring too much about it. It simply tries to stay away from it the minimum necessary to feel "comfortably safe".
The Maine Coon was on top of the scratch post when I started the first time the robot, and she followed it with the sight all the time without getting down from it.
I noticed she's very scared of it and she always tries to be in a different room from the one of the robot, but still she always try to keep an eye on it to see where it is.
The real problem is that she isn't scared of it only while it's wandering around, she act weirdly all the day, taking glances at the robot by time in time and walking "flattened" when she's near it.
She's usually very social and isn't scared by visitors or anything, she's genuinely curious and never scared. So I'm wondering why she's so scared by this vacuum robot?
The weird thing is that the european is the one that usually gets scared by noises and visitors!
They are both scared by my ("old") manual vacuum and always run in a different room when I use it. Because it's much louder than the new vacuum robot.
Attempts to fix the problem
I tried to make her play near it while it's turned off and to feed her still near it, but she's still quite scared.
How can I make her accept the "new kid"?
