One year ago smokey was dumped at the end of my driveway. here he is napping with my daughter in her fridge box fort about 8 months ago I could not figure out why I was smelling cat pee/spray all the flipping time.. everywhere I went I smelled it... Hubby thought I was loosing my marbles... that was until we started to re-do the office and found the corner of the desk.. corner of the book case.. wet.... so we ripped up the carpets and OMG the amount of pee/spray was UNREAL.. now bear in mind that during this time the cats were only allowed upstairs because my moms dog had the run of the down stairs (we were babysitting him because of my moms house burning to the ground Dec 4th/10).. so from that point on Smokey was outside during the day and he was allowed to come in at night BUT he was to be crated.. when he was allowed out in the morning he went straight outside and only came in to eat shortly after breakfast. We fixed that mess the proper way and decided to look deeper.. we looked at the floors in my daughters room... same thing... corners soaked.... fixed it there and my room and the spare room...all the floors were sealed and then hard wood put in its place. We then found wet marks on the dining room floor... tore up the linoleum floor to find he had ruined that floor too. so now we have spent about $5000 on floors and vet bills and HE IS STILL SPRAYING!!! Smokey was taken to the vet.. he is neutered so thats not the problem Vet said blood work looks fine some counts are elevated bt still within normal ranges... says we can put Smokey on kitty Valium and see if that works... but that can get costly AND there is no guarantee it will work so now that the weather has started to turn cold again my daughter had been getting lax about making sure he stays outside and we have found him inside and she gives the excuse that its to cold out. IF we were to build him an insulated cat house in the front porch... and he will be fed out there.. the only time he will come in the house is at night and he will go straight to his crate.. in the morning he will go straight outside again and be fed breakfast outside.. then that way he can spray all he wants but will still be safe from night time predatory animals. Is this a humane solution or should we just put him down? The vet says he is a healthy cat.. no issues .. he is about 4 years old... no way of telling when he was neutered so this may because he was done late in life. he is just so loveable.. hes a GREAT cat... GREAT personality!
