[quote Oxford]’ve known these cats since she bought them about a year ago (helped pick them out) and had sorta accepted their lame, skiddish behavior, but now it is getting to me. They lurk in the hall until you walk toward them and then they friggin bolt for under the bed like I am a feline ax murderer (hmm, there’s a thought).[/quote]
Use a laser pointer as a cat-toy tool. If they bolt under the bed, have the dot from the laser pointer move about the bottom edge of the bed. They may start associating you with the red dot that is chase-able.
Don’t try to chase them down to pet them. Use the laser pointer dot to get them closer to you. Get them chasing the dot at a distance to you and once chasing, have the dot sometimes approach you.
It does sound like the cats don’t have much human contact even with your GF. The end result being that they are quasi-feral.
