Oh, my friend, my heart is breaking reading this. I am so sorry for your loss as Jack and I are all too acquainted with that pain, as are our cats who have grieved right along with us, after losing a "brother" or "sister."

Not a lot of people talk about this so I saltue you for writing it. Losing a beloved animal companion like like is a double gut punch. For you and for Cato. I hope the pain ebbs soon and you are left with nothing but loving memories of Lucky.
