Thanks. Today Méu skipped when I was getting some stuff in the kitchen and almost immeditaly searched for Patinhas. The latter was in submissive positiion and started howling (it seemed like it). I got Méu and put him in my room...

Now, Méu is in my bedroom and Patinhas is loose (he isn't used to being in a single room , only during the night). It seems this wil take longer than I expected :-(

I also clipp their nails because I was afraid that they hurt each other... Even with short nails they seem to do it.

Thanks for your comments. I feel more hopeful now and will talk to their vet about the options (calming down Méu, etc).

I'll keep up posted.

Maria
