Taco's Tooth Removal

A year and a half ago Taco adopted us after his last owner died a few months before. He's been pretty healthy but today (2/5/18) we took him to the vet for a checkup after he lost a tooth and had been coughing off and on. We found out that his bottom left tooth in the back is absessed and needs removed ASAp. Becuase he is an old cat they strongly suggest that we get blood tests done to make sure his body can handle anesthesia and then cost of the surgery, antibiotics, pain medication, etc which in total comes to $395 (proof of cost will be attached). I have added $10 to the cost to cover the fees that GoFundMe charges. If you do not feel comfortable donating to a GoFundMe I can provide other ways for you to help if wanted. Please just contact me for that information. Thank you in advance.
Also after recent turn of  events if we were not stressed out enough about Tacos surgery, we're also needing to move. We are not in a safe living enviroment (unable to cook besides microwave, etc.) so we are needing to leave ASAP as well as get this surgery done for Taco. Some people know already what is going on with our living situation, and I am willing to discuss this in a private message if needed about why exactly our living situation is unsafe and why we need to leave.
