Fiona is in heat.

And I think she has developed attention deficit disorder. She plays with her ball for only one throw, then leaves it laying around. I gave her a new toy which is usually destroyed in 10 minutes and it still exists in 75% format.

Is this normal? Also, an odd question, do they get cramps like female humans do? I noticed that she was restless for about 30 minutes and heavy panting. I thought bloat, but that was not it.
