Siberian kittens & cats in New Orleans, Louisiana

I rescued her at 4 mos old from the rear of a Laundromat on a very hot day, 100°. The Laundromat mgr told me that she was dropped off by a lady who said she was "in her car and" she "didn't want her". She's got good behavior except that she's trying to rule the roost. She wants to rule over my 10 yr old fixed male house cat who's very sweet . He's raised a lot of kittens I found it adopted over the yrs (to train them for others who wanted a trained kitten ). But Honey has been peeing on the rugs all over the house to make her scent everywhere. I've tried the pherome sprays/plug ins, cat urine cleaners, catnip and treats. I let both cares outside at night and keep rear door open enough for them to come in. Honey comes in a lot to check up on me but during day when I'm at work she does her spray thing. My older car doesn't even want to come in house anymore. Im sure he's tired of her scent marking. She is very good and loving otherwise, but I think belongs in a home with no other cats.

My neighbor and I have started trapping/fixing cats in our complex. Sydney was our first to get fixed at Abadie Vet I have wanted to get another cat and Sydney was very friendly and seemed to have exposure to people. He would walk into my apartment every time I opened the door. On Saturday, December 13, I took him to Healthy Paws to get fecal test and tested for Feline leukemia and HIV. Also got him microchipped and his nails trimmed. He did great with all of the testing and came back negative for everything but the worms. He had his first worm medicine and flea meds and I was given second worm topical med and purchased 3 additional months of flea meds. I have receipts showing everything that has been done for Sydney. Unfortunately, I cannot keep him. He is very affectionate and is very much a lap cat. But he also weighs 12 lbs. and is very strong. For the past 2 days, he has repeatedly landed on my neck and upper back and my shoulders are very sore. I am 67 with COPD
