Cats eat Snakes...
I believe I will be the first to answer "Yes," but I would personally not do it.
I would think that a cat, or kitten, would have parasites from the litter box, or just from being feral in general, (eating wild lizards, birds, squirrels,
... and snakes, as well as drinking from standing water.)
They also have very sharp claws.
IMO, if one was going to feed a cat to a snake it should at least be p/k, or even better f/t and declawed.
Who is to really say what is "okay," and what is not.
IMO, It is never "okay" for the majority to infringe on the freedoms of the minority, as long as their actions do not infringe on anothers rights.
(At this point, we could argue what is, and what is not a true basic human right... but I'd rather not.)
My opinion is that every living creature should be given the same "respect," as any other living creature.
Why is it okay to mass produce rodents in a "puppy mill" for the sole purpose of feeding reptiles, but a moral crisis to feed a cat to a snake ?
That said, I don't think it is wise to film a video of a snake eating a cute little kitten on youtube, in order to try and get a reaction from those that find it appalling.
The majority in the Hobby feel it is wrong, so you can imagine how those that do not like snakes to begin with feel.
I am sure it is also more of a culture shock, because our members from Vietnam are probably

wondering what the problem with using cats as feeders is ?
