Boris medical emergency

As some of you may know already, my cat Boris, has some unexpected health issues. She has been extremely lethargic, not eating or drinking water much, and seeming rather weak. Last night I took her to an emergency clinic and payed $290 for an evaluation, only to be told they could not find anything wrong with her without having to blood work and x-rays. The total cost for all of that because it's an emergency clinic, and had I gotten those things done there it would have been around $1,200. I have contacted a vet clinic to see what estimates may be to get these things done as soon as possible but am still awaiting a response. I would like to start getting funds together so I can get to the bottom of what is causing my best little friend to feel so bad and get her back to living her best little life. I have set the goal for this at $1,000. I do not know if this is too much or too little, so I might need more, might not. If for whatever reason it is less, I will issue refunds evenly to all donors. Thank yall for any and all support
