We have four indoor cats. Last night I was petting Panda, and I found what I think was an engorged tick on his neck. I decided I would take him to the vet this morning to have it looked at and removed. But guess what, this morning the tick is gone! Besides being freaked out about having ticks in the house, do I need to be worried about Panda at all? Do you think I should I still take him to the vet? We will be thoroughly vacuuming and washing the bedding (as he slept with us most of the night). Any other advice? Thanks.
