Hi and welcome to Pet Talk!

The cats international site - http://www.catsinternational.org/ - has the best articles I've ever seen about behavioral problems.

You might want to check the article on "Spraying problems can be solved!" which includes inappropriate urinating.

If you think it's due to tension between the cats, take note of their comments about Feliway. A lot of members in this forum have tried it to reduce tension and they say it works!

Also, I hope your vet has ruled out any medical problems. If not, a checkup is in order.

My RB kitty also urinated on the bed after we moved. She did get over it, though.


Good luck to you.

Pat
