Delilah had been doing great. She was using her litter box like a champ (and occassional poo that plopped out, but never pee’d outside her box).
Suddenly, a week ago, thats all changed. She sometimes goes in her litter, and other times, she goes in the corner near my cabinets in the kitchen. She also never poo’d anywhere in the house (shes free-roam) and now she goes wherever she pleases. Due to this, Ive had to put a gate in the kitchen so if she does mess, its easy to clean.
We did discover, delilah is a HE not a SHE, but out of habit, I still call him a her and kept her name lol 
Nothing has really changed at all. We plan on getting her fixed next month. Im not sure if its a hormonal thing because she is coming to sexual maturity… Im not sure what to do about it…
Any help, advise, tips would be GREATLY appreciated. It seems she wont even poop in her box anymore… im constantly cleaning up piled of poop in the kitchen ALL day.
