I've been battling an ant infestation the past few days--they've been going after Tiffany's food dish. I've finally moved his cage to a new, ant-free part of the house, but I think the ants were biting at Tiffany's nose whenever he went to eat before, as he's developed a swollen red spot on one side of his upper lip. I monitored the swelling for three days and it hasn't gone down. I've made a vet appointment for Friday in case there's any infection, but in the meantime, has anyone else seen something like this before? Do you think it's irritation from ant bites, or something else? Is there anything I can do to help treat this? Thanks!
