Being transferred into carrier to be taken for spaying. As we tried to recapture her, she spied the opening into the space between our first and second floors. This space is also where our electric panel (covered/closed) and data/power lines run out of to the rest of the house. She was up and into that space as fast as lighting. One of my son's reached to grab her and I screamed for him to not touch her for fear she would bite and shred his hands and anything else that she got a hold of. This was Tuesday morning, the 14th. Our college son, who has studied the behavior of wild animals as part of his coursework, immediately shut off all lights and sources of sound and said we all needed to leave immediately to have the best chance of her coming out. And so we did. We have not seen nor heard anything since, save some faint sounds at the other end of the hole she went into. We have tried to take pictures and see if she is there but are seeing nothing definitive. College son suggesting that tonight we put some of the leftover salmon from dinner with some water in it to see if we can at least determine if she is still up there or is downstairs hiding somewhere. At least this way she will have some hydration, if nothing else. Husband is concerned about her bathrooming up there, but more concerned that she may expire if we don't have evidence that she ate anything. Anyone know of any ways to get her out without destroying the house or lines in the process? College son has suggested borrowing a special camera/snake/noose tool and at least seeing if she is there and where "there" is. Husband thinks she will come out on her own, given enough time. But isn't against putting out some food/water, but he doesn't want her to make a mess up there either so I am walking a fine line on the subject. He likes cat's but says she is more of a wild animal at this point and will act as such if we try and do a lot more. Any and all thoughts and ideas (as well as prayers that she comes out on her own and we discover that rapidly enough to block her re-entry) are most welcome! Thanks!
