Abandoned pet cat, Menifee, CA

I'm doing this out of desperation. Kizzy Aimee is a sweet, shy cat whose owner is leaving her behind bc she's moving in with ppl with allergies. Shes spayed, litter box habits fine, gets along with dogs, and may be put to sleep if she's not adopted or fostered. Shes an adult:dont know age. Please, does anyone know or live near there who can help her? Shelters are full.
