Why does my older cat bite the back of my younger cats neck every time I leave the house? It's the only time he does it.
protection. Since you, who your cats consider "mother" is leaving, the older cat sees it as a duty to protect the younger one. Cats will often carry kittens by the backs of their necks in times of unsafe situations.
maybe to stop it running out the door
hes asserting his dominance over the others ur home ur the dominant
Showing the young-ens who is still boss! The little ones are testing him.
The cats call that brotherhood or sisterhood.
The older cat is protecting them by carrying the scruff on the kittens neck.Mother cats do this often for protection.Dont worry,The mother bites it gently so it wont hurt the kitten
It is a sign of dominance
