ok so about two days ago jack threw up twice but it was watery and there was hair balls in it so i figured he just threw up a hair ball... now two days later we woke up and jack threw up cat food alllll over the place.. as i was cleaning it up he threw up again.. so later "about an hour" he threw up again.. so all together he threw up about six times this morning.. i got on the phone right away with the vet and he said that he probably just ate something like a bug or what ever.. he told me to watch him and keep an eye on him.. so jack laid in the same spot all day never moved.. no food, no water, no bathroom.. until about 11 at night he started to walk around and wound up throughing up but it was watery and bubbly.. im guessing cause he didnt eat or drink today.. it was to late at night to call the vet and now jack is back to sleeping.. what can i do for him till we go to the vet..?? how can i tell if he has a fever..?? and does anyone know what is causing it..?? eating bugs..?? wiskey our other cat is perfe
