My male cat is 15 years old. Has been treated for thyroid for past year. Now developed
vomiting and diarreah, for about a month. Vet wants to do exploratory surgery. Cat is an indoor cat, however, was on leash and caught an earthworm and ate it about the same time the vomit/dirreah started. Could the worm bring on the vomiting and diarreah
for the past month?
