Quick question on normal kitten breathing and heart rate

Kind of an update on my little orphan. We've had her for 2 weeks now and she is doing really well. My question is-I noticed while she's sleeping (which she does a lot after tearing around for a bit) her breathing is quick-like she has a pretty fast heartbeat. Is that pretty normal for a 5-week old?

if its after play I wouldn't be concerned. Kittens and cats will change breathing patterns as they sleep as well. If gums are pink and not pale and she seems fine, i don't think I would worry to much.

Yes, she seems fine and plays really hard, then she crashes equally hard. Thank you!
