Oh I most certainly do complain about that. I have no problem with people owning mutts as they are often times so much better as a family pet than their purebred counterparts. What I have a problem with is someone selling an obviously mixed breed animal as a 'designer'. They are mutts. Cute mutts, but mutts.
As far as snakes go I do like the look of some hybrids but I can't rationalize breeding them, myself. Or buying one for that matter.
In dogs, you can have accidental litters. In snakes there are very few species that go out and do this willingly.
I know there are some subspecies where this happens, but they are already very similar. I'm have kind of mixed opinions, and they're sure to have changed tomorrow.
Speaking of mixed opinions... Dogs are the same species. Snakes are not. Yup. My opinion just changed from the time I started writing this post to now lol.
Morphs ARE what 'designer breeds' are in dogs. Hybrids are a totally different subject.
