Awwww ((hugs)) I am so sorry for your loss. I love cats and have them myself and so does my sister. She had to put one of her cats down a couple of years ago and she was so upset. Your cat is fine and will always be around. I always see a cat in the corner of my eye at home and its not a cat I have had before but he or she is around all the time lol. So I really do believe in them being around you.
