I have a hard time dealing with death. To me, it means the person (or animal) who has died now ceases to exist. At least in this world, even though we're pagan and believe in an afterlife, no one is 100% that there is an afterlife.
And belief in reincarnation aside, as far as we know, we only get this one life.
We recently lost another cat. After losing three cats to a landlord who took them from us and released them into the wild, losing one of the cats we hid from her has been a severe loss to all of us. But to me more than any of us I think. Mainly, because I blame myself for not doing more to prevent the loss of the first three cats because I was afraid of being evicted. I also blame myself for not seeing the signs of illness in Anubis sooner.
