Thanks for all your advice
I used a spare cage for indoors so I could stay up with her all night to watch for any ‘signs’ of maggots or worms, and I could ring the vet if needed. I’ve been awake with her for far longer than 6 hours, and she seems to be just fine. She’s ate her normal portions of food today, as well as plenty of water. I’ve checked her over a few times, especially around her rear end. Thankfully, there was no sign of maggots or worms.
The weather has been really warm over the last couple of days in the UK, so the attraction of flies is probably normal. I’ve gave her a worming tablet today and kept her dry and warm throughout the night, as websites recommended. I think she’s in the clear now, as she’s showed no physical signs of distress, and has been doing her usual exercise and food pattern like normal. I think I’ll keep her in for an extra night- but is there any sublime symptoms I should look out for?
