So sad for your loss. When we lose something or someone we love it causes all these
emotions inside to start wondering and searching for the Whys and What fors? in life.
Thank you for relating that information concerning Hartz products........when your kitty was having those reactions to the collar, did you remove or leave it on?
There are many kitty lovers here who will give you hugs and sympathy, you need it right now along with your other little kitties, they know something is wrong........so cuddle them a little more.
