Yes, it can. OTOH, it can be fairly fast. A fast delivery is more likely if this isn't her first litter. Do we have any idea how many kittens there are yet? She will deliver each one individually, but once the first one comes the rest should be faster, as her cervix will already be fully dilated. Also, once the first one comes she won't be caring about other kittens, only hers.
she's still panting and insisting on being with Wy nd the babies. I hd to move them. This can go on for hours, right???
She's not pushing yet, right? Once that starts it should be fairly quick.
