We have three cats. We take them for yearly check ups & vaccinations. Those visits are not cheap (in my opinion), but we get a 10% discount for multiple cats (which doesn't amount to much). Our cats are older, so we have the usual older cat problems. Our oldest one had a cyst removed and dental work last year which cost quite a bit. We spent a lot on our old girl who passed on 2 years ago. She had some health problems but she lived to be almost 20, with a good quality of life. Having companion animals can be costly, so I would advise people to consider carefully before making the big commitment.
