Hello, I’ve just taken gizmo for his check up. The vet said when examined he passed a large volume of sludge and advised on doing an X-ray to check for stones. So have left him there to do this and they talked about maybe performing a bladder wash out too, using a catheter or something.
he also advised to keep him off ‘the greens’ (asked if I give him lots of kale which he’s not had for over a year). He said just the occasional bit of carrot or apple he can have

What have I done leaving him there?
obv he’s not a piggy savvy vet and this is costing me a fortune.
I’m really not wanting to go down a surgical route if it is stones as I’ve never had good experiences with guinea pigs and surgery or rather anaesthetic and I can’t provide the intensive aftercare he will need (Feeding 2 hourly throughout the day and night).
a few days ago when his anti-inflammatory ran out i noticed a difference in him, he started staying in his bedroom more and his tummy/bottom was wet like he’s dribbling urine out In little bits. He’s still eating and I’ve been syringe feeding him emeraid sustain, his weight yesterday was 978g but the day before was 996g. I weigh him at 3pm so haven’t been able to do it today. Can anyone advise I’m quite worried.
