I just think it's funny.

I think here I need to explain exactly what I mean by "newborns not being able to feel pain." This was too blunt and not specific enough, and now that I read it I can see myself arguing against myself.

What I mean by this is that at such a young age animals have developed no real personality quirks. They feel sensations. Here wombing is exactly right. But sensations are made more extreme by the understanding of them. For example, a girl breaks her wrist. It hurts yes, and this makes her cry. Yet she also understands that she will not be able to write or play baseball in the upcoming tryouts. These all are very relevant.

Correct me if I am wrong, but a human baby would not have anything near this simplistic understanding. If a baby gets a cut, the baby will not understand that it is bad because it will sting whenever she gets salty food on the wound. So therefore it hurts, but there is no specific understanding.

The newborn kitten understands even less than the baby. If we're talking about humane killing, the cat feels nothing in the sense that it may feel a sensation, but it's almost immediately over. I guess that could be considered humane.

Now what most people here are imposing are morals.

This process is not less legal than euthanization in shelters. And personally, I'd rather kill kittens at newborn age when they have no real personality traits yet than give them to a shelter when they're weened and they have developed or are developing this personality. That's even more cruel. They are very likely to be killed then.

There are special situations in which this must be done. There are special situations in which special tactics must be used. For example, Cookie, who had the litter of which we killed a few, was adopted. We took her in from the streets. She was a lovely cat. We didn't know her age and were planning on fixing her. However she disappeared for three weeks and came back pregnant. Why did we not fix her before? We did not know her exact age and didn't want to risk fixing her early. We told the vet about her and he agreed. The kittens were killed humanely.

After that we had one litter of which we kept all of the kittens. We're planning on having another litter sometime when we're ready for it. Just some lovely European Shorthairs, simple farm cats, that we can raise.

I should have explained all of these things in more detail, but I was in a hurry whenever I wrote the posts at the beginning of the thread.
