My goodness, there is far from being a pointless thread.
I totally understand how you feel about your Tex having just loosing my heart kitty Katie last month. You say you haven't really had the time to grieve for Tex with everything going on with precious Sammy, well since Sammy is doing so well, I think now is the time to let it all out. When you are alone in your home, take a picture of Tex and let him know how much you miss him and how much he meant to you. Cry like you never cried before. This is what I did about a week after my Katie girl was gone. It helped me some and I pray that it will help you also.
You will know when the time is right to welcome Tex home.
I had a hard time also coming back to Cat General, but I figured if I didn't do it soon, I wouldn't be able to come back for a long time. Debbie, T & P's Mom, was the one who helped me with this. She said it helped her to jump back on the wagon when her precious Tubby passed on, and believe me, it helped me also.
I still have LES when I see other tabbies and you will also when you see other tuxies, but it does get easier with time. Your tears will be replaced by smiles just thinking of the wonderful memories you had with your beloved Tex.
In regards to Georgie, you definitely did the right thing. You loved her enough to do what was best for her. It sounds like she is quite comfortable being at Grammy's and you will still be able to see her.
Sorry this is so long, but my heart goes out to you.
