Those Really Aren't Puma Prints, Are They?

John and Anthony woke up to the sound of someone singing, Happy Birthday. Anthony crawled out of his tent. "Someone's celebrating a birthday up here on the trail," Anthony said. 
"I don't know about up here, but today is Denise's birthday," John said. You can sing her a song if you like."
"How is she going to know that I sang it?'
"Mushroom would tell you that she'll feel the love. And isn't that what really matters?"
"I'll sing, but you gotta sing with me.," Anthony said. As they sang Happy Birthday to Denise, Anthony pulled out his camping stove to heat up for water for coffee. But when he came back out of his tent, he saw footprints all around his tent. He walked around his tent and then around Johns. The footprints were around John's tent, as well. 
He asked John to come and take a look. They both stared. "They aren't bear prints. They are cat prints," John said.
"Big cat! Do you think it could be a puma?" Anthony asked. 
"I'll have to assume that he was just checking us out, whoever he was."

"Do you think that Mushroom is writing about us?" Anthony asked. 

"I know he's been tracking us and letting everyone know where we are," John said. "Knowing him, he's probably making up stories as we go along."

They went down about 3,300 feet and then climbed up about 1,000 feet.
