10 days can be a long time, despite the best laid plans, etc., you can easily be looking at a discoloured or green pool. Lots of variable, including hot spells. What I do is buy the regular sized bleach containers and have whoever is feeding the cats while I'm away put in a jug every two days. Mark dates on them with marker if you want. The idea is to keep it really quick and easy for them, and I know the chlorine level is good. For this period of time I figure keeping the Chlorine high enough to prevent a bloom is the #1 thing, and I can balance out PH, etc. after I'm back.

This is for an inground 32x16, so if yours is smaller, space the jug to 3 days or whatever you need. I also invite them to use the pool as much as they want, as I like to have it stirred up. My pump is on 24/7 since I don't have a timer. It's cheaper and easier than having to shock, filter and vacum a pool back from a mess.
