My 4 months old cat has been acting weirdly these past few weeks..he litters everywhere (1-2 times at one period at different places first the feces is a bit hard but the second one is softer) although i provided the litter box...and funnily sometimes he went into the box but his @ss is outside the box...and he's been vomiting here and there which looks like his dropping (greenish)..planned to go to the vet today.. :-(
