We need a pool!

We have a yard big enough for a pool but we can't afford an in-ground pool so we may just buy an above ground pool for this summer.  We really want to be able to enjoy it without having to leave and go to a waterpark. So I will be doing some research and hopefully I will find something, I have seen some websites to research especially on the supplies needed so maybe will buy a pentair pool and get it set up but then again its something I need to think about as we have cats that live in the neighborhood and roam free.  I need to do my research first!
