We weigh his lordship occasionally and I notice his weight goes up and down. Do I need to worry? These are his reading this year (yes, I record them, it's like pussy cat Weight Watchers!):
19/01 - 5.2KG
26/01 - 5.55KG
16/02 - 5.5KG
19/05 - 5.4KG
13/07 - 5.35KG
31/08 - 5.25KG
Does this look reasonable? He's gone up and down but is about the same as he was at the beginning of the year. He eats normally (providing it's what he fancies on that particular day) and doesn't drink any more than he used to.
