Khloé Female Cat

LOST PET ID: 70078181


Denver, CO 80210

White patch on her chest and lower tummy. One white toe on her right hind paw, the rest are black. She can't really meow if she tries it sounds like a kitten crying . It's definitely not a normal meow. Inside of her ears are pink with almost freckle like marks that are brown and she looks like she is almost balding her hair is very thin above both eyes and she's kind of on the smaller side for being eight years old sometimes she's skittish yet at the same time she wants to explore and check things out.

Lost Male Cat last seen CR 38 & CR 7/3rd Street, Mead, CO 80513

Reported 5 months ago, updated 2 days ago

Aslan Male Cat

LOST PET ID: 69773496


Mead, CO 80513

UPDATE: He was seen by several people on CR 36 between CR 3 & 5 around the end of November. Someone has likely has him indoors, but if you have seen him or know where he is...PLEASE, PLEASE, PLEASE contact me!!! He was last seen at on 11/08/23 near CR 3 & CR 34 Mead/ Berthoud area. Very large, intact (unless he /has been neutered after he left) male; hazel-yellow, somewhat crossed eyes; long hair, but has been trimmed some; large mane; white chest and stomach area; hair tufts on ears and paws; hair mats easily though; his color can appear to be any of the following or combinations of cream/white/orange/red/ginger/tan-tabby pattern up close or in the right light; and he has a lion face. The hair on his tail is normally very long and bushy, however, I had recently cut some burrs and mats out of it, so it can appear choppy. He is friendly with our family, but would not likely go to just anyone. Like most cats he only wants attention when he asks for it.

Frequently Asked Questions

I lost my pet. What should I do?

Take advantage of online platforms – they help you get the word out, quickly and easily. You can report your lost pet to PawBoost in no time flat. We’ll send an email alert to our local members, post to the PawBoost-powered Facebook page for your area, add your pet to our lost & found, and make a lost pet flyer – all for free.

Other sites that help you raise local awareness for your lost pet with minimal time and effort are Nextdoor.com – a PawBoost partner – and Craigslist. Both of these sites have very active lost & found sections mainly used for lost pets. We highly recommend you use these resources in addition to PawBoost!

Visit your local shelters and animal control agencies in person. Details can get lost in translation over the phone and that might lead to missed connection.

If chipped, make sure your pet’s microchip is registered and up to date. If you don’t know your pet’s chip manufacturer or number, your vet should be able to help locate this information.

Put up flyers and tell your neighbors to be on the lookout. The more you engage the Thornton community, the better your chances of a happy reunion!
