Isabel, I am so sorry that I haven't seen this thread until now. I have had a busy week and didn't have time to log in to Pet Talk until now.
I am shocked and it's really hard to find the right words, just know that you have a lot of people here at Pet Talk who care about you and are willing to help you with whatever you need.
I am so sorry that you lost your husband so suddenly, it is such a tragedy.
Sending hugs to you and your family, Milly & Izzy send comforting purrs.
