So recently my dad's cat has been sick and not feeling all too well. She is throwing up a yellow liquid and won't eat or drink. We have taken her to a vet and got her examined and had an injection of liquids (i think to keep her hydrated) and the next step is to get her blood taken and tested to see if theres anything else Is there anything I can do to make my cat more comfortable in the mean time? She is also just isolating herself away from everyone else and I don't want my dad to be heartbroken if she passes away. (hopefully not) Should I leave her alone or what should I do? He asked me to try and make her as comfortable as possible so please give me suggestions on what I should do.
