Sometimes it comes off in time, most times it doesn't. I wouldn't try to pick it off you may end up with a hole. Timmy tried that one, he tugged and he tugged and he tugged until it came off, with a big chunk of fleece! His other trick is to pull the bobbles off of bobble mats.
I agree, most of the time it just stays….we have a fleece pad thats been round the wash multiple times and it still has a small boar glue spot. I would recommend just leaving it, and it will lessen over time.
That's a polite way of putting it - not what I said! He was looking at me as he did it, the expression said 'you can't stop me'.Oh Timmy!
I've got loads of very old pee pads, last winter I made a dozen new ones which are thicker and much better quality. Every new pad has glue on it, the old ones I'd be happy to throw away have none!
