A bit of a long story about how one time we had cats that really did view us (my family and myself) as parents...

One of our cats (we still have her, she's an old crotchety thing by now! >:3 ) had a couple of litters of kittens before we had her spayed. The first time, she raised them alright, but the second litter she essentially abandoned entirely. We had no idea why, she just refused to show any sort of interest in them.

So, we stepped in and hand-raised those kittens from birth up til they were ready to go away to new homes. We took turns bottle-feeding them with kitten formula round the clock, including in the middle of the night; we kept them in a nice warm box with blankets in it, and several times a day we'd give them a full on "bath" with a warm washcloth like their mom should have done with her tongue.

It was a lot of work, but DANG those were some cute kittens.

I think they grew up alright in spite of it all. They all ended up going to good homes. I'm sure some of them are still around today.
