Sear the rib roast (prime rib) for 15 minutes at the higher oven temperature (450 degrees F.), then turn the oven to the lower temperature (325 degrees F.) for the rest of the cooking time. Every 1/2 hour, baste the cut ends of the roast with the fat accumulated in the roasting pan.

A mother cat can be spayed when her kittens are eating canned food regularly, which is typically when they are between 5-6 weeks old. A mother can be returned to her kittens to nurse them 24-30 hours after spay surgery.
The best time is at 5 to 7 months of age before the female cat goes into heat for the first time. Sometimes vets do it as early as 7 weeks of age. The vet authors of the above mentioned book say that early spaying does not cause health problems or long term behavioral effects. Hope this helps.
