Hi! Been a while since ive posted here, but i have three rats- about a year and a half year old. Theyre all from different litters, and one has a respiratory infection she spread to her sisters. My concern is that shes developed 3 medium sized tumors in the past few days- and though i know its common in rats i want to be sure its not a result of the infection. I have been doing breathing treatments but i cannot afford a vet visit nor do i have rat vets near me, im a minor with no job & cant drive. Is it possible for me to give her small doses of dog & cat allergy/kennel cough treatment??
