I am so terribly sad to read this and I absolutely feel your pain and can totally empathise with you, having lost my beloved Fosco to FIP last November, he too was a cat that was always with me and the pain I felt when I lost him was terrible. I still cry if I see photos of him today so I know how you feel, then only a few months later I lost my darling Mittens after a dental procedure, she too was my lap kitty and they left me feeling absolutely devastated.
Please accept my heartfelt condolences for your loss, I know that not everyone out there understands the heartbreak we feel at losing a beloved fur baby, but I believe those of us here on the forum know and understand how you feel.
When you feel ready, here is a step-by-step instruction guide how to post photos on the forum, please feel free to let me know if anything is unclear and I will do my best to assist you.
Thinking of you, I know just how devastated you're feeling right now.
