Hydrangea flowers turning yellow

I bought and planted this pink Hydrangea mophead last weekend and the flowers are already turning yellow. The leaves are also browning in places.

We have cats so I'm wondering if this is due to cat urine, or possibly under/overwatering or too much sun?

Any suggestions please?

    It's possibly transplant shock. To have a hydrangea in flower like that on a comparatively small plant and at this time of year makes me think it has been brought on under cover.
    See what others have to say  :)

    Yes I thought flowering was strange, but assumed it was maybe due to the warm weather or the species. The tag says flowering July-October.

    It'll have been one of the forced ones that are often sold in spring.
    The flowers will be going over now. It'll be fine next year and should flower at the right time  :)
    It's a place where beautiful isn't enough of a word....

    I would cut off the flowers that are going over (cut the stem back to the first set of leaves), that will take some of the strain off, as it were. Give the plant a chance to get its roots established :)

    I'm reluctant to cut the flowers as new ones have been appearing every couple of days. If I did, will it flower again this year?

    No - it won't flower again this year. The only reason it's flowering so early is because it's been forced to do that. 
    Taking spent flowers off is fine at this time of year. Normally, when it's flowered when it should, you'd leave them on to give a little extra protection over the colder months, and especially at the end of winter when new growth starts, as it can be vulnerable to frost at that point.  :)

    Yes, l wouldn't remove the lot @andy1977, just those that are going over at the moment. It's a bit like taking off a jumper on a warm day, you then feel better and it's less of a strain on your system.

    It probably will continue to flower as it's been conditioned to think it's around August time, and as @Fairygirl says, the old flower heads act as protection over Winter.
    Next year it will have sorted itself out and be in the right time zone, as it were :) .
