*2 Before: SILVERMAN, TALLMAN, and N.R. SMITH, Circuit Judges.

Travon Thompson appeals pro se from the district court’s summary judgment in his 42 U.S.C. § 1983 action alleging violations of his right to free exercise of religion during his pretrial detention. We have jurisdiction under 28 U.S.C. § 1291. We affirm.

In his opening brief, Thompson failed to challenge the district court’s summary judgment in favor of defendants, or any other district court order, and therefore Thompson waived any such challenge. See Smith v. Marsh , 194 F.3d 1045, 1052 (9th Cir. 1999) (“[A]rguments not raised by a party in its opening brief are deemed waived.”).

We do not consider arguments and allegations raised for the first time on appeal. See Padgett v. Wright , 587 F.3d 983, 985 n.2 (9th Cir. 2009).

AFFIRMED.
