Dear fellow guinea-pig lovers,
we have an 18-month old male guinea-pig who last night tipped the scales at 1.5 kgs! His weight has been creeping up steadily.
He is a very nice, extremely tame guinea-pig but he will not take any exercise - if you put him down on the floor, he just sits there or runs for the nearest cover and then sits under that.
Any ideas and suggestions gratefully received!
