In reading through the Solensia for arthritis thread, I'm not sure if I missed it - but has anyone noticed any slightly 'odd' side effects? Rosa is a 20 year black and white moggie, with pretty severe osteoarthritis in her front legs resulting in very limited mobility. She's got declining kidneys, and on twice daily gabapentin and one prednicare (very low dose) on alternative days. All fine but it was clear that she was finding it hard to move about and use the litter tray easily. Our vet suggested Solensia as we'd tried everything else that would work with the kidney issue. All fine at the time, but about 36 hours after the injection, Rosa started to vomit (mainly biley water), had a ranging thirst and seemed to have what amounted to some sort of seizure - shaking slightly then sort of froze. She also kept losing bladder control and was clearly distressed. This lasted about half an hour, then she went to sleep - breathing fine. We kept monitoring and everything went back to normal. She does seem to be less uncomfortable walking now - but only change we noticed was her poo. This became softer (still solid and definitely not diarrhoea) and a more yellow colour. We used to have a diabetic cat, sadly now passed, and it was much more like his poos. We're now at the end of the month, and her poos are being drier and darker. I see on other forums that the second and third injections can give odd side effects - so has anyone else had this sort of reaction? Can't say I'm keen to take her to the vet again (she always gets very stressed anyway) for only limited improvement and potentially worse side-effects.
