No, you should not trust a negative fecal. You could still have parasites. The way my vet explained it to me is that a fecal test is only done on a small sample of the stool, it's like a long film that you only cut a part off. There could still be eggs (which is what they look for) in another part of the sample so just because it's negative doesn't mean that the animal has no parasites, just that there was no eggs in the sample they tested. When there is reason to suspect parasites, like with a stray, it's a good idea to do two fecals from two different parts on the stool sample.
In my opinion you should always deworm a cat when it comes in to your home, whether it's off the street, from a shelter or from an owner. It doesn't hurt and is something that should be done on a regular basis anyway. I treat all my new cats with either Frontline or Revolution and Strongid for worms (in my opinion Strongid is the best wormer and it's very cheap too). If they have fleas for sure it's a good idea to treat them with Drontal too since they are very, very likely to have tape worm (from swollowing fleas). I'd still do a fecal on a new cat though to check for things like coccidia and giardia. If it's negative but they have symptoms, like diarrhea, I repeat it.
Good luck with your new kitty.
