Found siamese cat (Onion creek)

Update: Brought him to Austin Animal Center and no microchip was found so they took him in for processing and hopefully on to adoption.

com/ASTNFound/Details/ASTN/A892941 Found white/brown siamese cat in our backyard in Onion Creek.
Friendly and warmed up to me.
He/she has what looks to be a flea collar and their back left leg is partially amputated at the foot.
Looks well taken care of but want to make sure no one is missing their sweet kitty!
