Oh no! I feel so bad for both you and Jasper. I'm sorry there's still no answers, and I hope the lump isn't malignant. It could just be a random bump or just a fatty tumour, which are usually benign. I'll keep my fingers crossed for you and Arthur sends great big puppy kisses to you and Jasper! My gf and I are going to light a 7 day candle for you guys, and give you an extra dose of magick! Keep us updated, ok? And give Jasper belly nuzzles from me!

Chin up, kiddo! It will all work out in the end!
