Ive had my cat now for over 6years..himalayan... We used to live in another location ...where we first got her till she was around 3...and we never had litter problems. Now since we moved and have been living in a diff place now for 3 years..on and off she quits using cat box... Been to vet mulitple times.. Just this week actually...vet said she had bacteria n her stool... Gave her antibiotics...however.. This has been goin on for 3 years on and off...we tried 2 boxes...diff litters...diff location... Nothing works... She will usually poop some in her box...but will always be some on floor n house...or all on floor... Any ideas ?...
