The owner of the kittens have the right to give the animals to a person they will feel give it the best home. To be decietful in your intent is wrong. If you want that kitten for food, you should be upfront and say that.
On the other hand, what if you give your kittens away to the pound thinking a good home will be found. After a few weeks pass, the pound still has not found any good homes and decides to put the animals down. They have the option to gas it, or to give it to a reptile owner for food. Whats do you think of this? the origional owner thought they would be given a good home. In the end, is dead, dead? Or is there a certain dishoner in death by contriction that you wouldnt want your animal to suffer?
