Me and my fiance just adopted two Maine coon cats from someone on craigslist and upon bringing them to our apartment they seemed really skiddish and hide for a few days before coming out for about ten minutes at a time while we were laying down. This is when we were able to pet them and noticed they are malnourished and one is almost severely underweight, while the other still skinny for her age of almost two years has what feel like hard lumps on her the skin of her right side near the stomach. They seem abused or at the very least neglected. My fiance and I don't have a lot of money for vet visits as we are both students. What or where can I go for cheap or free to get my cats looked at and/or what can I do to make them healthier.
