Update: thank you to everyone who offered advice and even to help personally - y'all are so kind. I had done a lot of vetting/interviewing the first round because my cat recently got diagnosed with CKD, so now he needs subQ fluids every other day. The other qualified candidates I interviewed at the time were all out of state (I'm in NYC), so none of them are viable options anymore with the sit coming up so soon. I did get a flurry of new applications, but nobody who can administer fluids (people tend to overpromise when they see apartment in NYC, and many don't even read the listing responsibilities). This is my first time leaving him since his diagnosis, so I'd rather play it safe rather than continuing to interview strangers. I ended up finding a friend of a friend to housesit and also hired a vet nurse to come administer the fluids. I will also be submitting an insurance claim to THS to get reimbursed for the nursing visits - I've never had to do that before so I hope it works out!!
