I’d avoid the shelter route, if at all possible. Even the “no-kill” ones could be a poor experience depending on how well your cat handles it.
One thing you could try is a site like Nextdoor if one exists for your neighborhood. Local social networks like those can sometimes be helpful with simple things like rehoming pets. They also come with the annoying drawbacks of most social sites, ( i.e. douchebag members ) so buyer beware.
There’s some group that helps arrange transport for pets by linking up people (like pony express) to hand the animal off to the next ride, I’m not making this real clear but maybe that would be a way to get that kitty from **Polarius **to you. If I were anyplace on the route I’d help but I’m sure I’m not. I wish I knew the name of that group…
Our local humane society takes surrenders as a last resort - your local humane society may too.
The cats at our humane society are treated very well. They have a huge indoor/outdoor cattery and lots of attention from visitors and staff (and lots of cubbyholes to hide in when they don’t want attention). I don’t believe they euthanize any cats. The cats typically adopt out quickly. If a cat is having a hard time being adopted, they will waive the adoption fee. You may be able to find an equally good humane society in your area. Good luck!
If he were permitted to take his cat with him to another country, chances are it would be required to be quarantined for at least six months. Better for the cat to find a new home for it than to make it be locked up a cage for that long.
If you haven’t already, Facebook and Reddit. It’s one of the most consistently reliable ways get people to adopt a pet in my experience. Take some cute pictures, tell a sad story and encourage everyone you know to share it. You’ll eventually get connected to someone who would love to have him.
My cousin just chose to give up a impulsively acquired kitten (long aggravating story that makes me hate my family) and after posting to Facebook had like 3 takers in an hour. Granted she’s a 20-something girl and the cat is still a kitten, so pretty much ideal circumstances, but still.
If kitty is a specific breed, are there rescues for specific breeds? I know these organizations exist for dogs; don’t know if they also exist for cats.
Would you like the option of getting the cat back upon your return?
Maybe a foster who would appreciate some help on the food and vet expenses exists?
On the plus side, you are in an area of high density people and money, so options are a bit better.
