She can't be rehomed for the same reasons you don't want her in yours. But you could ask a cat rescue to take her in , on condition you pay for her lodgings and vet care for the rest of her life.

Both will cost you money, but our beloved pets deserve the best we can do for them.
A better word than 'apologise'?
