No, it doesn't sound weird to me! I volunteer with the small animal rescue here, I know first hand the detrimental consequences of not fixing the buns! Females need to be spayed or they have an 85% chance of getting ovarian/uterus cancers :/ I know first hand what its like losing a bunny to this terrible disease too.
It cost me 250$ 5 years ago to spay my Acacia. Obviously females cost more bc of the invasive surgery. Males might be around 100$, I don't know- depends on where you go. They need isoflorene gas and sometimes bloodwork so cost adds up!! bunnies HAVE to have tiny veins! lol
