Oh my.
I saw your initial post, but, did not respond because I was (and still am) so far behind here. My apologies for being late, yet again, and my deepest condolences on the loss of your dear pet.
Besides the 2 dogs we currently have, we've had 8 previously over the last 27.5 years (3 at a time twice, and 2 passed when they were just puppies - so heart-wrenching).
Even with having had so many, It never gets any easier.
6 are buried in our back yard, and 2 were cremated, and youngest DD has their ashes in her room.
Again, sorry I'm so late, and my deepest condolences on the loss your beloved kitty.
