I've had my own cats, & did some fostering of cats as well. I like having cats in my home for protection. That's how I see them. They see what I cannot. Although I've been seeing some things as of late.
I miss having a cat around.
I hope you will feel better soon & I send loving light to your husband.
You could always try changing the "air" by fostering some kittens.... if your other cat allows it. They are funny! & demanding of our attention.
