Very sorry too for the loss. We had our cat for 16 years, I never knew how silent the house is without him.
A true story, one day I'm riding to my mom's house on my motorcycle. I see one of the people from her neighborhood start driving away from their house. I happened to glance, and on the roof, there's a cat just sitting and watching everything like its a movie. I start waving my hand frantically for her to stop, she's worried when she rolls the window down because I've got a full-face helmet on, and I tell her "You've got a cat on your roof." Now that was a surprise for her, luckily she hadn't gotten more than a few feet and the cat just walked down the car and back to the house, I think I heard him muttering "humans". :shock:
