as much as we can, in otherwords as much as we can afford, and how much my dad can afford because he has to help us with vet bills when we have them, but my animals needing a vet is is very very rare occasion. I dont know how much it would be but we could never afford more then $2000 in vet bills, there is no way, my mom only works part time, and I cant handle a job with school, when I can barly handle school.
