Jealous kitten

Mittens loves you so and you love him back, but a homeless cat hot jealous and jumped in your arms, kicked your beloved kitten out and rested in your arms, “they are my human now” said the cat. Mittens looks at you with sad eyes, wondering why you already left it, but it doesn’t know the cat actually kicked them. WHAT DO YOU DO?
