I got the impression that Gizmo would have preferred to be an only cat, instead of one of four. He much preferred the company of his humans to the company of the other cats. When they still lived at the old house, with the big yard, where they could all go outside to play, he would wander off by himself, instead of joining Casper and Patches in the frog hunts. He was originally adopted by the Daughter, but ended up with his Mom. Something happened that must have really bothered him, because when the Daughter would come to visit, he would hide from her. Gizmo was the only cat who liked to have his belly rubbed. He would even ask for belly rubs. His Mom is really missing this. Gizmo wasn't a loner all the time. He would occasionally join another cat for a nap, but these occasions were pretty rare. Gizmo was nearly 15 years old and his health had been failing. He was down to 5+ pounds the last time he went to the vet. They found a cancerous mass while feeling for his kidney. The vet thought that the tumor was operable, but in his already poor condition, it was very likely that he wouldn't survive the surgery. His Mom felt that it was much kinder to just send him on his way to the Rainbow Bridge, so that is what she did. Gizmo's Mom has really been through a lot lately, with both her Daughter and Son having had surgery recently. They both came through very well, but the anxiety must have been terrible, and then Gizmo's passing on top of it all. She really could use all the support we can give her.
Cancer led Gizmo right up to the Bridge.
His Mom helped him cross, which really took courage.
Now he can leap and run
And have lots of fun,
But we are sad because he has gone to the Bridge.
