Help Neo with his bladder (round two)

My name is Lys Morton and this here is my cat Neo. Back in 2022 he was in the Nanaimo Veterinary Hospital dealing with some major urinary crystal issues. Since then we've been on a specialized diet and such with the knowledge that these might one day come back after a bout of stress/major life changes/what have you.

Tuesday morning blood was spotted in his litter box and further monitoring showed Neo was the source (he has a sister, Riley. She's her usual opinionated self). While Neo remains in well enough spirits that he's attempted to ambush Riley numerous times and does seem to still be eating, he is showing signs of struggling to properly urinate and spots of blood remain.

A series of financial unfortunate events (including a recent trip to the vet already due to projectile regurgitation and a change of diets) has put me in a spot where I can't quite cover the costs and am hoping for some help. Currently we are looking at $200+ for the visit and examination and $200+ for expected antibiotics to help whatever UTI might be brewing. I am, at the same time, bracing for the possibility Neo will need a bladder flush like last time, which will add at least another $400 to the bill (last time it was well into the $1,000 range, we're desperately hoping that's not the case). I currently have the goal set to the smaller amount estimated but might update if things go sideways.

Photos attached of the meds prescribed Tuesday for proof as I currently do not have a bill or sale or cost break down.
