Don't seem to have a problem with them, but I have a cat that is an absolute murderess. My only problem is with squirrels, but I have a couple of .22s that are minute of squirrel head accurate and I'm in the country so shooting is not a problem.
Mine have food and water available 24/7 in their attached/enclosed/secure run. I see no need to take it up. Further, I am not willing to get my butt up at 5:30 AM to put food and water out nor to take it up/put it away after they've gone to roost at night.
