Thank you. Ok:so far. Mochi doesn’t seem interested in pulling out the stitches. Tumours are very common in pet rats. We had a squash ball sized one removed from a rat once, thought she would be ok and woke up the next morning to a bright and bouncy rat with a three inch gaping maw where the stitches were. Vet stapled it all this time and it took around 7 days and nights of constant supervision and an improvised sock vest (one of the boys old baby socks with holes cut out for arms) but she made a full recovery and lived for another 9 months. Amazing creatures.Yikes - sorry to hear that, fingers crossed for a full recovery!
