My cat travelled from banglore to hyderabad through flight on saturday. He was fine until the flight departed. From then he is so stressed until we reached destination even in the cab. He panted 4 times since then in the home and is breathing in this way. He is eating well and drinking water too and his stool is also good. Is it okay for the cat to do this if they are in a new place surrounding new people? What can be done to make him feel normal.
