While I was at work, my roommate sprinkled ajax powder all over the tub and left it there with the door open and two cats in the house. When I got home Moosh had a light dusting of powder all over him. I have no idea how long it was on him with him licking it off. I washed off as much as I could. Then he seemed to feel fine, he's been eating, but he threw up some food last night. From what I'm reading he doesn't need to go to the vet unless he vomits excessively. I'm very worried about him but I can't spend my rent money bringing him to the vet if all their gonna do is tell me to watch him :/
