Weird and concerning behaviour.

[Iulikk]

Hello! Last night, I was listening to music at a low level of sound, when my hamster suddenly started running (he hasn't been active a lot lately, and because of a tumor we had to remove his right foot) and aggresively squeaking, only for him to then stop and lean on his back with his feet up in the air. Since last night, this series of events repeated for about 2 times while i was awake, and 2 more times since i woke up, probably even more times during the night... I am really scared and don't know what to do, help??

Hello and welcome to HC!

I would take him back to the vet who amputated his foot because this vet knows him already.

I hope the vet will be able to help your hamster.
