My baby tortoise has an upper respiratory infection, hes on antibiotics and drops. Hes also had a feeding tube fitted as he wasnt eating on his own and had difficulty breathing, so stayed at the vets for a week. He came home when he was a bit stronger and started showing signs of improvement (eating more active etc) so i thought the infection had cleared up but this week things seem to have declined hes only eating pellets, sneezing not very active. I dont understand has the rns returned ?????
