Thanks venus, we did that 2 weeks ago and there's no infection, I wish it was that simple.
There's a mass in her bladder, could be a stone, cyst, tumor.. hopefully they will find out today. The incontinency is getting worse everyday, she's just leaking all the time. She tries to clean herself continiously but I think this cannot be good for her either... we really hope they find a solution.
Our other cat (her brother) is getting very aggressive towards her (they've always got along), we think maybe because she smells bad..
