I'm wondering if it is worth it to put a collar with an ID tag on Lucky, he is indoor only and microchipped. BUT he is 14 years old and has hyperthyroidism which makes me worry. I live in Alabama and I'm sure you've heard about all the tornadoes that swept through. Our house is fine but there are a lot of misplaced pets out there. Would the microchip take care of everything in the case of an emergency? I read somewhere that people are more likely to try and rescue a cat with a collar.
