This morning I found a puddle of pee a few steps away from the litter box that had a layer of foam or froth on top. The urine was a normal shade of yellow. I have two kittens (7 months, female and 5 months, male) and I'm not totally sure which one did it but I think it was the female cat because she was in the room when I found it sniffing the urine.
We currently have three litter boxes but are planning to reduce to two since there are two that they use almost exclusively. With the exception of a few incidents where both have pooped over the side of the box instead of in the box, the cats have never had a litter box accident.
I called the vet and was told that this isn't necessarily urgent and that I could wait and see if there is another accident. I'm a bit concerned; however, from the reading I've done on foamy/frothy pee, especially since my female cat, Pia had azotemia at 10 weeks due to some problems with her spay procedure (issue was resolved after two nights in the hospital on 24/7 IV fluids, thus far all blood/urine tests have come back normal).
Both cats are super active and are eating and drinking normally.
Has anyone had this issue before? Would you recommend that I immediately bring them to the vet for a check or is it possible that this really was just a non-health or behavior related accident? I don't want any potential problems to get worse but have spent so much on vet bills already!!

Thanks for the help! 
Good news then!!! Cats vomiting up bile from time to time is nothing out of the ordinary and not a concern. If it is beginning to become a daily issue, then I would offer food throughout the night to keep the stomach acids from building up.
