Cindy - I found this article to be helpful when I had to have Brownie pts.
Meowzer did grieve a little. Even with all the other cats around. He was the one that was always with Brownie. It took him a bit to figure out Brownie wasn't coming back. Of course with all the other kitties here he seemed to be back to himself in a week or so. But he still sleeps on the top of my catchall in the same position he did when Brownie slept next to him.
And another site......
Assumptions do nothing but make an ass out of u and me.
We can stick our heads in the sand for only so long before it starts choking us. Face it folks. The pet population is bad ALL OVER THE WORLD!
