yes thanks babygirlyorkie....... as soon as i saw that they
were in fact a perscription medication, i left the site.... i wouldnt buy perscription things online (not even my perscription contacts...lol)...... i will ahve to look into sentinel when toby gets neutered (next week i hope) and see hwo much they cost at the low cost clinic........ but the base price i got off the site that was suggested was helpful in determining if the vet i am going to ask will rip me off or not, anything over $50 for a six month dosage is too much...... lol...... least i learned somehting off the med site
