Hello!
Brilliant questions as always!
1- Good question. In these cases I probably would see what happened to the temperature with supportive care initially. I would be looking at other vital parameters too. It would also be worth checking haematology. If there were significant increases or decreases in white blood cell counts, that might also help with the antibiotic decision. If the pyrexia was persistent then I would consider antibiotics.
2- I use Vivomixx as it probably has the most evidence. I will often use Fortiflora in cats and Pro-Kolin is also a good choice, there is just a bit less evidence. I would go with Vivomixx when possible and definately in more chronic cases. In some cases, if the response is good, I would use probiotics much longer term.
3-Interesting case. Did you ever do biopsies in this case? It sounds like you have done a brilliant job with this case and tried everyting. Honestly, my next step would be a faecal transplantation. Do you think the owners would go for that?
Hope that helps.
Scott
