It takes some time for them to live in harmony. Tiki tolerated Coco for many years but the last 2 years as they both got older was different. Tiki started choosing to sit and lay near Coco which was always what Coco had wanted lol.
Coco always deferred to Tiki. The rule around this house is that Tiki is the boss. If Tiki wanted to drink out of their water bowl, she just went in for it. Coco would back up, sit down and let her have her drink.
I miss their interactions together but look forward to how Sugar and Tikis relationship will progress. We already know that Tiki will be the boss
