Cat Chat Feline Forum

I have two cats from the same litter who have been bonded since the day they were born. Never a fight (except play) or any aggression towards each other. Every year I bring them to my father’s for the holidays. They don’t like the car at all and meow the entire hour and a half long ride, but when we get there, they usually settle down after a few minutes. They may be a little apprehensive and skittish but nothing drastic. This time, I let them out of the carriers and the moment they locked eyes, they started hissing at each other. They won’t go near each other. Any idea how to get them back on track or is this going to be a long week?
