I'm sorry it took me so long to send these condolences. I get really emotional about the cat losses, especially. I know so well that terrible feeling at the beginning of seeing all their things, but not seeing them around the corners, on the beds, and in all the places.
I'm sure you are still so sad, but time does help.
If you want to adopt, there are so many young and adult cats waiting for a loving home. Follow your heart. We never can replace the ones we lose, but we definitely can channel that love to another sweet soul.
Much love to you and your husband.
