Please Help Apollo get his Biopsy surgery ASAP!

Hi friends, My name is Alli and if you know me, you probably know my beautiful and effervescent cat Apollo whom I adopted in 2017. He is now 11 and still very much loves life, hanging out with his humans, and going outside in the garden.

I took Apollo to the vet this morning to check out a lump on his back that has grown significantly in a short period of time. He has also been feeling lethargic and doesn't want to eat all of his food, which is SO not like him.

The doctor performed a growth cytology and determined that the lump is a cancerous tumor. This lump needs to be biopsied ASAP to ensure the cancer does not spread. Any help at all, big or small, would mean the world to me and my best Catfriend. Thank you!
