I was in the Southern California Thomas Fire. I took my cat with me to the shelter and he stayed in the car with his carrier and litter box. He was visibly shaking when we came home. He seemed to be all right for several days but was a little jumpy. He is now after several days of being home having a flare up of his IBD. Can cats experience PTSD? Could he be having a stress related reaction do you think? I know I am but not sure if animals experience this also.
