The Oregon 10-Day Pet Violation form includes both a FIRST NOTICE and FINAL NOTICE. The first gives the resident 10 days to remove the unauthorized pet or the tenancy will terminate. If resident is compliant in removing the pet in 10 days, the tenancy does not terminate. If at anytime within 6 months of the first notice another unauthorized pet is on the premises, the final notice can be served. It's a 10-day notice to vacate without another grace period. The tenancy would terminate in 10 days.
