Cats do experience separation anxiety. My boy wonders the house looking for e calling out and his meow sounds like a cry when I am in hospital. He does it every day for the entire time I'm in for. I'm usually in for up to 2 wks when I have my TIAs.
NOT TRUE!!! They can experience separation anxiety!! Yes they do communicate with other cats by meowing. Mot in all cases but they do!!! I would not believe all this person is trying to sell tell you is accurate! So, hence just because it's on the internet DOESN'T MEAN IT'S TRUE!!
