my cat (adult female) was diagnosed with parasite infection recently and already had her medication. her next appointment is going to be this Thursday..
yesterday she vomited what i thought a hairball, i thought it was normal.. but today she vomited again it was very nasty and i saw small living worm with it. is this caused by the medication to get the parasite out of her? or should i take her to the vet?
am i right to be worried ??
