i brought one of my friendly feral kittens inside back in February due to her not seeking out one of the 6 shelters in subzero sleet/snow conditions i had watched her for over 2 hours waiting for her to seek out one of the 6 warm kitty shelters i have for 9 Ferals but no luck she had stopped shivering when i decided to bring her in after a slow intro to the kitties of the house she was accepted however in the last month things have changed shes hissing at the others , and occasionally makes a growly groany noise at me and will fart in my face or in the fan or ac and assume the position unless i hurriedly take her to one of the litter boxes and put her in it she'll usually go pee on her own but i must drop everything and take her poo is this an issue i need to take to our vet is it behavioral something feliway could help or do i just have the strangest kitten in the world?
