Bruno and Tyson's End of Life fund

Bruno and Tyson have been inseparable for almost 11 years now. Bruno, with the darker fur, has terminal cancer in the back of his mouth/throat with just weeks left. Tyson suffers from dementia and blindness so is totally unaware of people or his surroundings.
We wish to let them go as they came into this world, together forever, so we would like to plan for a cremation together and have their ashes returned to us, together forever. 
Following a very large vet bill for Bruno, which uncovered his cancer and prognosis, we simply cannot now afford to let them be together forever, unless we can get help to do so.  
Thank you, if you can help us to achieve this.
