I am so, so sorry for your loss. I am relieved your beloved's pain & suffering is now over.
The perspective of being "humbled" by experiencing such unconditional and deep love from your lost loved is a healthy and positive way to look at things. It always helps me to remember to be humbled. To replace grief with being humbled to have ever known such miraculous love.
I have a foster rescue kitten with me now that I named "KID" who also brings me things. I have never had a cat that carried things in their mouths from other rooms. It is beyond adorable and makes me laugh. To see this small Tuxedo cat, with a black mustache (which looks like Charlie Chaplin) carrying a colorful toy in its mouth to me, from the other side of the office building where he is being raised. Yesterday he brought two different toys, a wand with a feathered plume (which is larger than him) and a wool ball, to where I work on my computer and set them beside me to tell me he wanted to play. And he is only a few months old.
I hope you and yours continue to travel through time now and heal. Please know that you are not alone. Your little girl is still with you in spirit and we here on the forum are also with you.
Kind regards and my sincerest condolences,
