He's old, 14 1/2. He's been a neutered inside cat all his good life. But he is continually marking all over the living room curtains and the youngest kids clothing. I'm ready to shoot him. I know it's from the damn feral strays and he's just doing what cats do. But I'm still ready to shoot him. I swore I'd not do any more trapping but I am at my wits end and have no choice. I'm going to have to trap these damn cats then block off any access (as best I can) to the front porch to keep them outta here. Hopefully that will get my cat to stop marking because washing the curtains nearly every other day plus cloths plus the youngest just told me he went in a corner in her room --- grrrrrr. Have to go clean that now . . . . . . .
