Emergency Surgery for Sirius

Our fur baby decided to eat something that has caused a severe bowel obstruction that needs surgery to remove. They need to perform an ultrasound to see exactly what the blockage is and how to remove it. It could end up tearing through his intenstines which would be fatal.  We've only had 9 short months with Sirius and we can't afford the cost of the ultrasound or the surgery by ourselves. Steph has already spent what she can in order to get x-rays but they weren't able to determine exactly what and where the obstruction is. We've called several animal hospitals to see if they can perform the ultrasound for less but it will be at least $450 for the ultrasound alone. We're remaining hopeful for Sirius but his condition has worsened since we first found out he was sick. We're asking for any help to keep our little guy alive.
