['My 15 year old cat passed away recently. It hurts really bad. I spent a large amount of my life around that cat.', "Oh no, I'm sorry for your loss. Cats are such nice companions.", 'She was a very friendly cat. I will miss her. Hopefully I feel better as time passes.']
Yes, time will help get over those feelings. Do you plan to get another one?
My pet cat passed away. She was 15 years old. I am very sad about it.
