He has also started to...

Moko is in a critical status now. It's started on 31 Dec. - he had a problem with his hind legs. He had a major convulsive seizure yesterday midnight. The seizure has gone but his all for limbs are paralyzed now. He just lays on his side. :/

He started this sometimes ago, but it might be a kind of sigh of this... I don't think there was something I could do if I had got it as a sigh, though.
