Hey hun,
There's a lovely cattery in Farsley which is in the West of Leeds. I prefer to have my cat looked after at home, but i've used this once and it was lovely...
http://www.cherrytreecattery.co.uk/It's all indoors, completely sterile with an isolation pen for sick cats - i'd use them without hesitation again.
I think that there's a MyPetStop in W. Yorks as well and i'd Google where the local one is - they're quite expensive, but professionally run and have extra luxeries (like TVs for the cats etc!)
There's also Greengates Cattery which is up near the airport in Yeadon (North West Leeds) which used to be a rescue and is a nice place and well run.
I also know a couple of wonderful cat sitters who may be able to help (although they minly cover the Leeds area)
Hope this helps!
