Thanks everyone for the advice. I figure, we'll put their food downstairs in the basement (Where the litter boxes are) since there's nowhere comfortable down there for them to lay. I'm gonna go buy 3 or 4 of those cat dancer toys and a laser pointer this morning. I'll have to discuss with the rest of the family about getting a new, large play structure.
For 5 years, the cats free roamed. It was probably about as safe as it gets, just short of having acres and acres of property. We live on a street that goes no where. 25mph speed limit, and the only reason to drive on it is to get to the houses on it. Unfortunately, it looks like someone recently put poison out for something. My neighbors cat and mine both fell victim to it
It's a very very hard transition on the cats, but we're all willing to do whatever it takes to keep them safe and healthy inside.
