Beverly, first I would like to Welcome you to Pet Talk.
I'm sorry that your first post had to be such a sad one. But please know that we all know what you are going through. It will be 3 years on October the 9th that I had to make the painful decision to put my precious soul kitty Katie to rest and I also went through the "What if's." I'm sure we all have. Trust me, it doesn't help with the healing part and you will learn to get past it just as I did. Just knowing that they are free of pain and are happy and healthy up on the RB, makes it a little easier.

Medusa said what I wanted to say to you, but she put it so much better than what I would have. The love for your precious Grey, just jumps out as I was reading your beloved memorial to him.

Congratulations though on adopting an older cat that otherwise would have spent the rest of his life in a cage. I thank you for that and I'm sure that Grey is very happy with your decision.
Maybe when you feel up to it, you can introduce yourself in Cat General and let us know about your new addition Poppy. I also have a Poppy who is a rescue.

Take care and may your beloved Grey Rest in Peace.
