Wow, Julez, that indeed sounded mean, kind of XDD
I just had a little episode of worrying about them. They're like my babies... They might annoy the heck out of me sometimes, but I still don't want them to be gone out of my life ;>_>
Cotton's heart is fine according to the vet, she said it's probably just an easily stressed out ratty, that's why the slight anomalies in heartbeat :)
Cotton became a hero today, we donated 1ml of her blood to another rat who was bleeding out and had a long wait for another donor, so the echo scan was completely free thanks to that and we got a permanent discount for all surgeries if I understood her correctly. And hopefully we helped another rat :)
Because of the blood drawing, Cotton should refrain from surgeries, so we rescheduled them both for next Friday.
Candy took her medicine without any fuss today, tried it with a banana this time

The bump doesn't get smaller but I'd be surprised if it worked so quickly. Still hoping it will work soon.
@Julez: Well, if you had plans like drinks etc, then it's more worth it to stay, since you liked the people so much.
I forget other people aren't anti-social like me XD
