It is nototiously difficult to breed from Captive Cheetahs - so any attempts must be applauded.
Chester currently have 3 males (of which 1, Matrah I think is the recommended male to breed from) and 2 Females (1 currently in Quarantine) both which they will attempt to breed from, so all of the characteristic cheetah breeding difficulties not withstanding fingers crossed for cubs next year (always an optimist) - On a similar note both the Asiatic Lions at Chester and the Sumatran Tigers have been mating (or playing at it in the case of the Tigers) which started an interesting discusson in front of the group of junior school kids that were party to an eyeful on the day they visited - humerous indeed!
