Poor little Tiki! That must have been some encounter he experienced. I'm so happy to know he's on the mend, prayers are being prayed for a complete and quick recovery!
Please know that I do understand your decision to let him continue being an indoor/outdoor kitty. Some things just can't be changed especially if Tiki has always been allowed to go outside. Maybe he'll be a bit more alert and aware of his surroundings now when he's outside.
Would you give Tiki some get well scritchies and smoochies from me?
