Very worried

About this little guy.

This is Spike he is Drusillas brother, he lives with my dad.

I've come home and discovered he has a massive lump, maybe abscess on his belly, my dad says he noticed a swelling the other day but obviously didn't bother to actually have a look - it's massive - and from what he says about spikes behaviour I suspect he has been in pain for maybe a couple of weeks :(

Will be going to the vets first thing Monday morning, I just hope nothing happens tomorrow but I figure what's one more day! Right?

:(

Feeling angry and upset.
