I have a 13 year old Maine Coon Tabby, Precious. A couple of days ago I noticed a HUGE bump on her left upper leg. It's not round, but more oval. It just seemed to appear overnight. It is about 2-3 inches and when I lightly squeezed it it seemed squishy. It didn't seem to hurt her, but now she walks funny. Kinda like she is walking foward but sideways at the same time. Her head was slightly shaking...kinda like a person with parkenson's. I think that it's starting to hurt her now...It makes me really sad because I bottle fed this cat since she was only 2 days old and now, I just can't bear the thought of her dying after almost 14 years together. She has also been peeing and pooing in the kitchen. I haven't been able to take her to the vet because I won't get paid until the 16th. I feel so bad I can't help her the way she needs... Does anyone have any idea what could be wrong with my long-time companion??? Thanks..
