Yes you should adopt her, the cost is the same since you already feed her 😁 This is how I came to have 7 cats at home and 2 others that I take care of . My cats are mostly males because they start to wander as they get older and although they don't have litters, their suffering is terrible from fighting, hunger and abuse they receive from people because they are a nuisance. I hope you manage to catch him, you can use a drop trap system
