I think cats have an extra sense !!!
Sydney also always knows it , whenever we are planning to go out !! He posts in front of the door to the garage and puts that face on ................
Believe it or not ; but a few weeks ago I've booked his stay at the cat-hotel this summer (we go to France for two weeks ) ; as I came home , he sat there and kept staring at me .... I left the invoice on the table to show it to my husband ; two minutes later , Sydney sat on the table and spent at least 5 minutes to sniffle at that piece of paper ...... Strange !!
