Thanks for the reassurance, Andy.

I'm not giving him any more pills until I talk to the doctor.  I left a
message for her to call me.  There are two reasons for this.  I can't see
any reason to give him antibiotics if his bloodwork doesn't show an
infection.  Also, the instructions, which were relayed to me by an assistant
and are printed on the package, are to give the pills with food.  Except for
a small amount of canned food in the evening, both my cats are grazers and
eat when and as they please.  I can't make him eat on cue so I can give him
a pill.  Also, if I hover over him when he's eating the canned food, or
interrupt him to give him a pill, he'll walk away from the food.  As soon as
he finishes eating, he goes outdoors for a while.  I don't want to give him
the pills on an empty stomach, because I know from personal experience that
when pills are supposed to be taken with food it is because it causes an
upset stomach if they are not.

I'm waiting for her call.
