That's a good idea. Look for lost and found websites too. I once found a cat, Lucy, that had been lost from home for months. The owners had given up finding her. She had been living rough and was very thin but otherwise well. She was microchipped (I got the vet to check for a chip) and I was able to tske her home. Such joy for the family who owned her.......
You should add the city where you are from, so if somebody sees his profile and knows the city, perhaps they will contact you if they have him or know where he is.
Elvis is so beautiful and i am so glad you have added his profile to Picato. Hopefully someone will have taken him in and will be caring for him until they find who he belongs to. I hope they see this and return him to you. I will say a prayer for his safe return. Lots of love and hugs for you......xxxxxx
