I have 27 snakes right now, 3 aquatic frogs, and one tegu (not to mention the 100 plus breeder rats, all the mice, the 4 dogs, the cats, etc). For me it is not that bad, as I work from home, and I actually enjoy the maintance tasks of keeping up with all the animals (except the cats!! Those are my wife's!) I tend to feed everyone on the same day (but there is always one or two that won't cooperate and want to wait a day or two!). I spot clean as I need to (everyday someone seems to need something done), completely change everyone's water every day. It takes a few hours aday (but I am very meticulous, more so than most), but I also spend time handling different snakes each day (I don't ever try to get to them all in one day, not sure my hands could take that many washings, lol), so that accounts for some of that time.
On the weekends, we do complete cages cleanings and wipedowns (unless one of the big ones has shed and dumped, then it gets a complete breakdown and cleaning right then and there!).
All in all, try to establish a routine, but understand that living animals will rarely conform completely to a routine, and just deal with the issues as they come up. DON'T put them off, get them done, and you will be fine. The problems occur when you start putting things off (they will pile up quicker than you think!)
Just my $.02, now where is my change?
"To truly rescue an animal one has to provide long-term care that guarantees the animal's security for its natural life, because rescuing is more than removing an animal from a bad situation. Rescue involves restoring and preserving the animal's dignity for its natural life without stress, and this includes conserving the species as a whole for generations to come."
