I have been zapping for several days trying to get an experiment . Several times the zapper has zapped my pet into the experiment it already is. It's not just the waiting time that is frustrating but the 400k spent also.

(I'm not sure if it does this when trying not trying for an experiment or not).

Is it possible to program the zapper not to turn a pet into something it already is?

If its possible, yeah I think its a good idea.

I haven't used the zapper in eons - since at least before you could pay to zap experiments. Back in those days you could end up zapping the same thing regularly. I remember one pet kept being zapped into a swampie, again and again even though it already was one. I'd say that's a "feature" of zapping.
