ok...here's a quick update
...
i bought 1 new litter box..bigger then the one they had... as soon as i came home.. put litter in it.. tigger.. my male kitten was already sniffing it... and surely enough... he marked it quick!.. so i went and bought another litter box.. for my female kitten... and for a couple of days..everything was fine each one with their litter boxes... until earlier 2day.. my boy cat went pee in the kitchen floor...
so next week when i take him to the vet..i'll consult him about my kitten's lil problem... and have him checked for a UTI...
....thanks everyone!
