Hi.. My guinea pig Kaly has been breathing heavily and started coughing. Some days he looks better some days he's worst. He keeps eating but not like before. He's never really been that active but now he just moves to eat. I'm so scared I really don't know what to do, I don't have a guinea pig vet around everyone says they don't know if they can threat them , they want to charge to see if they canbe able to threat them. I don't know what else to do he's my baby and I love him so much and he's a really loving guinea pig I really want to help him but I don't know how. Is there anything I can do without the help of a vet? I wish I could take him to one but nobody can help me, I live in Puerto Rico and I feel like the change in weather has gotten him sick . Pleaseee help.
