4 Feline House is correct. Please do not declaw her in case she can't become an in-house cat.
I have done Trap/Neuter/Release on two cats in my neighborhood. Both come to my house every night for dinner. One will eat out of my hand and let me pet him on the head (only). But it took almost three months of sitting quietly every night while he ate.
I trapped them both, took them to the vet, and let them loose within a 24 hour timespan. The female bounced off the walls of the cage until I got her to the vet. I still can't sit on the porch while she eats. I have to watch from the window, even though she knows I'm there. Ghost, the male, was quieter in the trap. He knows I have dogs in the house so he won't come in. One day I hope he will venture in when the dogs are outside. I'd like to be able to let him have a doggy door of his own where the dogs can't get to him so that maybe he'll introduce himself to the dogs when he's ready.
There are two more cats that come for dinner at night. Ghost watches over them, and I swear he has told them it's OK to come to my house.
The vet here gives me a discount so I only paid $125.00 per cat for feline leukemia test, annual shots, rabies, and neutering. Also be careful that she doesn't scratch you when you try to pet her. They can be real quick
Let us know how you are doing. Just don't be discouraged if it seems to take forever.
