Yes they did a complete blood work which revealed nothing abnormal.
I live in Montreal in the province of Quebec in Canada.
Many years ago he had a few ticks back when I wasn't living in apartment.
Yes Bob did eat a ton of hibiscus flowers and leaves. I stayed with him at my parent's place last saturday overnight. He vomitted them sunday morning. There was quite a handful. I try to remove them when I go there but the hibiscus has just been moved indoors for the winter and it is losing a lot of leaves and flowers right now. He doesn't usually have this many.
