ohh yea! My family recently went to Puerto Rico and my sister came every day to feed my cat and when we got home, we saw hairballs everywhere.
When he gets stressed, he rips his fur out. Probably not normal but he shows you when he is angry.
I bought him a cat carrier today so the next time we take a vacation, he is coming with us!
The only thing is we use American airlines and it's $200.00 for a plane trip so that's why we didn't take him last time.
