Low Cost Spaying
I may make some enemies here, but I have to say that, unless a cat was really unhealthy to begin with (and then probably a spay at that time wouldn't be advisable anyway), I have never done any bloodwork prior to a spay or neuter. In my defense, I have to say that all of the 'pets' that I have done have been abandoned or strays (I've actually never had a pet from a pet store or breeder, but have had over 60 cats and 20 dogs in the past 10 years or so, re-homing some and keeping the ones no one wanted). What kind of bloodwork do they do for a spay, or what are they looking for? My vet always told me it was the anesthesia that could be harmful, if anything. Usually I found that animal sanctuaries (as opposed to shelters that destroy animals in a certain period of time) had good info for low cost s/n.
