Here's how I look at it. Withholding food for 2 days is no big deal. Think of it as as 'fasting' for cats. :-) Humans do it for detoxification/health (I did an 11-day water fast myself back in November), why should we think it's not good for animals? I sometimes have to pull an 'all-nighter' trapping, and I can't risk not catching who I need. Leave water out for them, but withhold food for 48 hours. They will be fine. Heck, in some cases, I've withheld longer. I maintenance-trap twice a year at my colonies (unless I see someone un-tipped sooner), so everyone 'fasts' twice a year. :-)
