MY rat has both here in his cage. I think both are nice but if i were to pick one id say CIA , just because it lasts longer.
I swear my rat was up for it any time for about 3 days after taking cia ( they say cia is 2 days, I say it's three)
If you want it on the spot use & gone the next day, then v, if you don't mind taking it atleast 1hr before hand and it lasting for at least 2 days then go for cia.
They are very good quality as I am sure others will be posting up here as well.
ENJOY! ;-)
