I'm so sorry about your health problems, and I hope you get better soon. That is really scary. And sorry about your boy, who was taken away way too young. I have yet to lose one of my cats....I mean, the cats I've had as an adult. I had a few when I was a kid that either ran away, or my parents got rid of, but I have not been through that pain yet of losing one, and I get so sad when I even think about it. My SIL recently lost her cat, and she asked me to come up to the vet while she was saying goodbye and I had to run out of the room, because I coudln't even think about it. So I don't know what I will do. And I'm just sad for you for losing your boy. Try to remember your good times with him, you will always have those memories. Hopefully he has some funny stories or heartwarming stories that you can talk about to help remember him. I love to hear those kind of stories, so if you need to talk about him I'm a listener.
Get to feeling better soon and hopefully your sweet girls will make you feel better.
