¶1delivered the opinion of the court:
¶2The only question presented for consideration is the sufficiency of the second and separate defense. A mortgage of chattels is a conditional sale thereof, whereby the legal title is vested in the mortgagee subject to the right of the mortgagor to perform the conditions imposed by the mortgage. Upon violation of such conditions the title of the mortgagee becomes absolute, and he is entitled to take and hold possession of the mortgaged chattels for the purpose of sale, according to the terms of the mortgage, subject to the right of the mortgagor to redeem pending *507sale.—Atchison v. Graham, 14 Colo. 217; Newman v. People, 4 Colo. App. 46; Crocker v. Burns, 13 Colo. App. 54.
¶3When, therefore, it was made to appear, as it did by,the second and separate defense, that the defendant was the owner-of the cattle in controversy, and entitled to the possession thereof by virtue of a chattel mortgage thereon executed by the plaintiff, the right of the latter to maintain an action in trover therefor was terminated. His remedy then was by a bill to redeem, or some appropriate action whereby his interest in the cattle could be protected. — Leapold v. McCartney, 14 Colo. App. 442; First National Bank v. Wilbur, 16 Colo. 316.
¶4Counsel for plaintiff urge that the defense under consideration is insufficient, because it appears that the note and mortgage in question were purchased by defendant subsequent to the commencement of the action against him. In support of this contention, Gibbs v. Gibbs, 6 Colo. App. 168, is cited, in which it was held that in an action on a money demand, a defendant cannot interpose as a defense, by way of set-off against plaintiff’s cause of action, claims purchased subsequent to the time such action was commenced. But that is not this case. Defendant does not plead the Wilson note and mortgage as a set-off against plaintiff’s claim, but as a bar to his action. According to the facts stated in the second defense, plaintiff’s cause of action no longer exists, because he has been divested of all right, title and interest in the subject-matter in controversy, save his equity of redemption. That cannot be settled in an action in trover. An answer, from which it appears that plaintiff’s cause of action has been extinguished subsequent to the commencement of his suit, states a good defense.—Drought v. Curtiss, 8 How. Pr. (N. Y.) 56; Bolander v. Gentry, 36 Cal. 105.
¶5*508The judgment of the district court is reversed and the cause remanded, with directions to overrule the demurrer to the second and separate defense, and for such further proceedings as may be proper.
¶6Reversed.
