She is grieving for her lost "toy". This is a approx. 5" piece of plastic twistie with a loop in it. This is comprised of little holes like a ladder, and about 1/4 wide. If you are familiar with plastic canvas used for crafts thats about what it looks like. She is always losing this thing, my daughter will come over and crawl around the floors looking under appliances, furniture etc. Sweetie will not accept any other similar piece of plastic. I've made her identical twisties frim plastic canvas, she sniffs at them and walks away.We have tried to give her other items similar to this lost item with no luck. She prowls the house and looks under everything. Its been lost for 3 days this time, and I see a change in her behavior. She is doing cat tearers through the house, running up and down stairs, clawing at the furniture, etc. I know someday we'll find this but where & when? I wish I could help her, I really feel so sorry for her. She's had this all winter, lost many times cuz she bats it & throws it up in the air, and loves it to death. What a memory she has. Have any of you had this similar experience & what finally appeased your baby?
