Pregnant Cat only wants to sleep/lay on hard, cold surfaces?

Pretty much what the title says. Yuki is due any day now and refuses to use her soft, warm, cardboard box to lay in. She only wants to lay on our desks in the office, even when I place food in the box, or sit by her after placing her in it. She refuses. I'm worried she'll have her kittens right on the desk!

Suggestions? Comments? I've already tried putting the box on top of the desk. She simply refused to lay there.

They often dont want to use their nesting box before its time, or even, first when the kittens are born.  Its form nature, they dont want their chosen nest is beginning to smell too early, to not attract predators.

Why she insist to lay on something cold?  I understand it happens with some high pregs. Several other forumists has had similiar reports.  I suppose they wants the chill, esp if it is warm.

At the same time, they shall have it warm, not to be chilled out... 

The though strucks me, as Im writing it, how is it with high preg women.   Dont they get sometimes waves of warm, feeling it is too hot?   And wants to be chilled?

Good luck!

My cat is doing this too! She normally loves lying on top of my bed but now refuses and is always sitting on the tiled floor.. I don't think she will have them somewhere dangerous, when the time comes her instincts will kick in

That is pretty normal especially if it's hot weather.  I think carrying around the extra weight in late pregnancy just makes anyone feel hot.  It can be extra uncomfortable to be so pregnant in late summer.  for cats as well as humans.

    and  Stefan also has a valid comment that some domestic cats retain the instinct not to use the nest too much ahead of time.

  When it is time that the kittens are born just make sure they are in a warm area away from drafts and away from bright light   ( in other words dont put the box in bright direct light because that will go.  

Yes, the box is under the desk, and we've covered it with a towel.

I woke up this afternoon from a nap to find Yuki acting a bit odd (heavy breathing) but I'm not seeing any obvious contractions. I've put her in one of the cooler rooms with some ice water. I think she just got too hot and the fan in the office wasn't doing it for her anymore. :c

We'll be rethinking on where to let her have her babies, in the meantime.

I have to add my inexperienced two cents-- we adopted our pregnant cat just before she gave birth when she spent three days straight on our concrete patio where it is was cool and slightly damp during a heat wave. I put a box out for her... I figured someplace soft was better for a pregnant cat, but she turned her nose up... until she had the kittens in the box. she wouldn't stay in the box until she had them, so in your situation I wouldn't worry much.
