Well...I’ve got my extension ladder, rope, small trap, food, gloves. Its a two story townhouse,....so I’m not sure if there is anything I can do. They have been throwing food up there for it.....the fire dept cannot be called (they would charge for help) and we can’t draw attnetion to the situation. It’s a feral cat. the Association there will just want to kill it if they find out...like they have done with at least 10 others.
Tie the trap via a rope to the end of the pole, then lower it onto the roof, and wait.
Or, bite the bullet, and pay a private service to come and get the poor thing. There are lots of contractors with "cherry pickers" used for stuff like tree-trimming, antenna service, etc. Probably wouldn't cost all that much, and there are far worse things to spend money on.
You can probably collect five bucks from half the people in the neighborhood to help out.
PS:
Make sure you are giving it plenty of WET (canned) food (and not the “chunks” type which is ALL suspect, IMO).
Cats need a LOT of water. They are “designed” to get nearly all their water intake via prey they capture. If they are eating dry food, they MUST have a LOT of water available. If they do NOT have water available, they MUST have wet food, to supply the water they need to survive.
Please don’t let that poor thing die up there. I’m sure you can find someone to step forward as “the owner”, to claim the poor thing, so that it won’t be killed when it’s retrieved.
