Ok, I have heard about parasites and worms prevention and medications and the whole nine yards. Is it possible that an adult cat that has had all the preventive care for this condition can develop it? I noticed some white thingies that look like seeds and for what I've read in the forums they might be tapeworms or something to that effect. I took a sample and it's in the freezer for the vet to take a look at it. I will take the sample to the vet tomorrow and I guess I'll have to medicate the two adult cats and the kitty. I just need some feedback based on your experience... BTW, the new kitty tested negative for everything in stool sample test that the vet performed. Advice, experiences and anything is appreciated.
