We have an 8 1/2 year old 18 pound neutered Black cat---[avatar]--named Toby---we take him with us in our motorhome---he is fine when we travel north and south but gets sick when we go east and west---vet just says "Oh well, it's Toby!!"---he also likes to chew stiff plastic bags ---doesn't eat them ---just perforates them--cats are the greatest!!!
