This cat showed up at my place just before a cold snap where it dropped to -3F (-15 with wind chill), I put out food and set up a box with a heat lamp, she's been coming back every night since and last night I was able to pick her up and bring her inside which tells me she's not feral but was probably dumped at my property.
It's called Stage Right from Monoprice, it's not a great kit but it was under $200
