I had a male (Boone) & female pig (Bella) in a very large cage which was plenty room for the two of them. Took very good care with daily hay, quality pellets, fresh water, and occasional fruits and veggies. Boone being around 8-9 months old and Bella around 5-6 months old. They were introduced around a month ago exactly when I purchased her. (I had Boone first for about 2 months). Today I woke up and noticed a very weird coughing noise coming from Bella and body contractions. I should have took to her to the vet right then but I can’t go back in time and do that now. Since today being my birthday.. I did a lot of stuff and came home very late to the coughs being much lower and it appeard that she was struggling to breath. I examined her further and noticed blood coming from here nose/mouth, and very little movement but she was still alive. At that point I figured the end was near and let her have time with Boone for awhile before she passed. No vet was available at this time only one 2 hours away which I knew she wouldn’t make. I just went in the room where the cage is and she was dead with Boone right next to her cuddling her. It broke my heart and I’d truly love anyone’s wild guess as to why she passed. It makes me really sad, she was very young and possibly pregnant.
