Again I have to agree...give it time. My big guy, Kunan, has always been accepting of the newest member of the herd but he is definitely a bit standoffish this last time with Scooter. Kunan is also very jealous and lets me know if he thinks I am spending too much time/attention on one of the others. I have made a point of,when I walk in after work or whatever, seeking him out first for hello hugs and scritchies so he knows he hasn't been replaced. FIngers and paws crossed that Tigger will soon realize the same....
