Look, I'll take the cadence point first and then see what Kristin wants to add in terms of Librela expectations. Look, sitting here, I would expect a roughly balanced cadence across the year. Now, let's take a look at Q1, which is a specific point you raised in your question, Jon. If you look at Q1, certainly, if you look at companion animal in the US, there's an easier comp. We had destocking the first quarter last year, clearly something we look to see as an easier comp that we come up against. But at the same time, you had a 12% growth quarter in livestock in Q1. And so, I think if you look balance - those don't completely balance, but it's livestock growth, both in the US as well as international. And then you have China, which clearly started to more deteriorate in terms of the economic conditions there throughout the year. So, that becomes a heavier, I would say, headwind coming into Q1 as well as the conditions, weather conditions in Australia, et cetera, having an impact there. So, I think if you balance those out, and last point I'll make is, Librela, clearly very pleased with how we exit Q4 and enter into Q1, but it's going to continue to contribute more and more as you go through the year. So, Q2 and Q3 would be more than Q1. Therefore, the contribution from Librela accelerates through the year and it doesn't have as much relatively speaking in Q1. So, when you take all those into consideration, I actually see a roughly balanced year. Now, we did make references to FX, so from a reported basis that again, taking a look at where the FX rates were a couple weeks ago, you do have a heavier impact in terms of both revenue and bottom line. On the FX factor, hopefully what we provide in prepared commentary is helpful there. So, that's the other piece you have to think about. But when I think about operational base growth, I mean, we did exit the year with good momentum as we exited Q4 and into Q1, again looking at US companion animal. But that's how I think about it. Now, is Q1 going to be higher than Q4 from a Librela perspective? I think if you factor about a quarter to a third of impact coming from stocking, that's $12 million to $15 million. So, even if you had a flat, that means you grew by $12 million to $15 million going into Q1. I won't call it exactly here right now. What I would say is we're pleased with how the product is performing, but we are still in the early stages of this launch.
