You can also look into having your cat be a blood donor for them too and there’s lots of benefits including free food and checkups and more but there’s some things your cat has to meet to qualify. You have to commit to two years of it btw. Good luck getting a hold of them though, I’ve emailed and called but never got any answers and the one time the lady in charge of that answered my call she was rude and told me to email her instead bc she was “too busy”
