So really? Three large carboys gassing off in a confined 8 x 10 room is not going to give any dangerous levels of CO2? You sure.....
Well I was being a little sarcastic..... BUT, seriously you would probably have to do those things I mentioned for the cat to be in danger.
Don't worry. CO2 can be dangerous but only by it displacing enough oxygen to suffocate you.
I'm not sure how many gallons you would need to brew in a very small room but it would be a lot, the room would be small and ventilation would have to be very bad.
Any indoor room is going to have air flow between rooms.
It's fine. It's good to think about potential problems, but you can stop thinking about this one.
Unless of course you duct tape a blowoff tube and the cat together. That might get the concentration that it would take to hurt him during vigorous fermentation.
