The Gattaca Mob was formed in 2001 by Whiskers females and Vivian males. Wahine took female dominance and Izit took male dominance. Wahine was lost and Risca became the long-term dominant female. Stinker took male dominance for a while till he was overthrown by his son Izit. The Gattaca never grew fast since Risca wasn't very productive. Compared to the Commandos, it took the Gattaca five years to have 33 pups while the Commandos only took one and a half years to have the same number of pups. Izit died and new Vivian males emigrated into the group, however they all died of disease. After Risca died none of the Gattaca females succeeded her and the group dwindled. The Gattaca was finally lost in August 2007.
When the Gattaca first form Wahine took dominant female over Risca who was weaken by the fight with Vialli. Male dominance was taken by Izit. The group came under new dynamics when Wahine predated and Risca took dominance. Izit retained dominance in the group. In 2001 Stinker the ex-dominant male of the Vivian and Izit's father joined the Gattaca. He took male dominance away from Izit and was dominant for three years until his son finally deposed him. Izit died and a new group of Vivian males joined Daffyd too dominance but soon died. There were no new dominant pair after both Risca died.
Gattaca was a minor mob on the hit TV show, Meerkat Manor. The group was only seen in one episode "Boys Will be Boys". They were only seen when the Whiskers wondered on to their territory. The small Gattaca war danced at the Whiskers who didn't want to fight. Being smaller, the Gattaca were more likely to loose a fight but the Whiskers weren't interested in fighting the Gattaca. Instead the Whiskers left the Gattaca territory, leaving the Gattaca alone. However later on Yossarian and Big Will went roving looking for females to mate with. They located the babysitting burrow where three or four meerkats were babysitting. Yossarian worked up the courage to go into the burrow with Big Will keeping watch for the returning Gattaca. Yossarian went down into the burrow hoping to find some females but only encounter Red Blooded Gattaca males. The rovers were seen off and the Gattaca were never seen again. The Whiskers moved away from their territory and now longer had encounters with them any more.
