What should I do?

I'll move this to the caring for Strays and Ferals forum. There are a number of people who monitor this forum and can give you a informed answer.

for wanting to do something for this kitty!

The first thing I'd do is make sure (s)he's spayed/neutered.

After that... it's a tough decision. If you're only allowed 2 and you're going to have 3 - this one would make 4...

I'm not sure what "not making a good indoor cat" means. Does he not use the litter box? Is he destructive?

Inside a different home, those may not be issues - they may require work. Do you have the time to give?

Something to consider... fostering him, and work on finding him a better home than his current situation, but not making him "yours." Of course, with an older kitty, this may end up being a lifetime commitment, so I wouldn't go that route unless you were prepared for that.

Awww, that's wonderful you want to help this kitty out!

[quote=marinewife05;2781603We aren't supposed to have outdoor animals at all. And we are only supposed to have two indoor animals. (I currently have that and I'm supposed to be getting one more kitten...shhh...don't say anything. )

I don't want to rain on the parade - but what would happen if they found out you had more kittens than allowed? Would you have to re-home the kitties?

I saw someone mentioned the other day, there is some form of arrangement for the cats owned by US military personnel, they do have free spaying.

If that is correct, it means the fixing/spaying as such is no big business. Unlike for the civilian rescuers. Although it may be easier if the owner does it before she leaves, not you as rescuer. Im not sure here.

Of course, finding new homes for the abandoned / left behind surely is the real trouble. I suspect leaving them behind is very common, and not all care to find a new owner - thus also abandoning is rather common.... *crying*

If they move and leave the cat behind....you can call the active duty member's CO and have them hauled back to deal with their pet. Haha---military justice at its best. But if you do that they might have the cat PTS. Probably dump it at a shelter.

AFAIK, there's no widely available free altering program for military pets. Although sometimes the base vet is cheaper than civilian vets.

If you are able to take the kitty in as a foster to find him a good FOREVER home I would do that. I get nervous when people offer to give away their pets so lightly. To me that says that they don't really care about the cat and in a situation like that he will always be at risk of being dumped or abandoned in one way or another. If she offers to give the can to you just like that she would probably offer to give the cat to any ohter person too and the next person may not be as caring as you. I'd worry about the cat if she brought him with her when she moves.

I'd also take the comment about not being a good indoor cat with a grain of salt. In the past year and a half I've taken in 11 adult cats and older kittens directly off the street and not a single one has had any major issues with becomming indoor cats. Most had no issues at all and some of these cats have lived on the street for years. I'm sure this kitty would adjust to indoor life too with a little bit of time and effort on your part.

Please keep in mind though that taking in an adult cat as a foster may be a long term commitment. There are so many adult cats out there waiting for homes and so few people willing to adopt them so finding a home may take time. You also want to find a good home that is going to make a lifetime commitment to the kitty, not just any home.
Before you take this kitty in please be prepared to keep him for a longer period of time. That doesn't have to be a bad thing though. As you say he is a real sweetie.
