What's that on the lemon tree?

I was given a lemon tree in a container as a birthday present back in March, and I haven't bumped it off yet so I must be getting something right.  I've been keeping it in the conservatory, but now the weather's warmer it's sat outside to take advantage of sunny days and frost free nights.  
What you might not be able to spot from this photo are the teeny-tiny green fruits on the lemon tree. They're mini-sized, but will they actually develop into proper edible lemons?  I've no idea, but we'll see as the weeks progress.  

The back garden's still home to a hoard of (mainly) tomato plants waiting to be re-potted into larger tubs. Lack of potting compost is the reason for the delay.  It's a drawback of not having a car that I have to get heavy stuff like compost delivered or ask a family member to give me a lift, or else stagger home from the local shop with a solitary 20 litre bag  which is as much as I can carry myself.  Okay, I'll put my tiny violin away.  Enough with the sob story.  
Now, on to a totally non-garden related matter.  The kitty cat ... 

Honestly, it's hopeless.  As soon as Em sees the camera she's as sullen as a moody teenager finding out there's no wifi.  I was hoping to get a photo of her stretched out and relaxing in the sun, but no.  So here she is with her 'yeah, whatever' expression.  
Right, I'm off to give to the tomatoes a much needed drink of water, then myself a much needed cuppa.
