Sundial, that was one of the first tests I requested and it was negative. I'll drop off a stool sample on Monday so we know exactly what is living in Harper's intestines. I know for certain she has tapeworms for I found several proglottids on her stool when I went out to pick it up and deposit it in the trash. The next thing on the list of things to do is to get her "fixed" before she comes into heat. After which I'll begin the vaccine regiment.
