I've raised £400 to To Help with tank's vet bill's

Raising Funds toward my beautiful baby boy Tank's vet bill. Here's tank's story. tank is 9 months old he came to us very young and i hand reared him. 03/05/18 he fell very ill with the symptoms of crying in pain, Struggling to use the toilet, wasn't his usual self very slow movement and distant, our baby boy was not himself at all, it was heart breaking to see him in such a state. At around 8:56 pm last night we called the emergency vets due to tank getting worse and his crying turn to wailing in pain, the emergency vet allowed us to take him straight in when we got there the vet checked him over to find he has a blocked bladder' luckily after more tests because of fears his organs might be failing they, arent failing at this moment, they have giving him medication to help with the pain they also drained his bladder and managed to get a small amount they also have put him on an iv for fluids to help keep him hydrated, he is having to stay with the vets untill he is stable enough to come home . vets told us it would be a 50/50 chance of survival through the night, but our baby boy was so brave and strong that he made it through the night . vets have said it was nothing of our fault and that 1 in 5 cats suffer with this condition. Tank's vet bills are already climbing up to £400. the vet gave us option one is to pay the full amount of the vet bills, option 2 is to sign tank over to the vets and have them rehome him once they have successfully treated him. as anyone would know its not an option anybody want's to take lightly because he is a member of the family no matter what happen's hes got a younger brother called leo who absolutely adore's him and isnt taking it lightly that tank is not around and would not manage without him not being home permanently he is already crying and searching for tank.
all money raised would got straight to the vet's for tank's bill' we just want our baby boy home safe and sound.
He's just not a cat he is our family and we are heart broken.
Even if you could only spare little it goes a long way, and every little helps
