It can be considered a faux pas to turn up to a party uninvited – let alone a gender reveal.

But one cat paid the ultimate price after returning home coloured in blue having gatecrashed a neighbour’s baby bash.

Pet owner Sophie Jenkin was taken aback at first when Wilbur, her two–year–old tabby cat, turned up earlier this week a lovely – albeit unusual and unexpected – shade of cyan.

‘I haven’t stopped laughing since Wilbur came home blue,’ the 32–year–old said.

‘Wilbur is actually a girl but we thought it was a boy so we named her Wilbur. But it’s a girl and it’s now blue.’

The admin worker in a local GP surgery said at first she was concerned local kids may have been messing about abusing pets by throwing paint at them.

But her worries were put to rest when she shared a concerned, yet tongue–in–cheek, post of her blue cat on Facebook on Wednesday – and the explanation became clear.

‘We thought something nasty had happened at first or kids were abusing cats in the neighbourhood,’ the mum–of–one added.

Wilbur, a two-year-old tabby, who crashed a gender reveal party returned to their owners in a surprising shade of cyan

Wilbur’s owner, Sophie Jenkin, washed him after she read that the dye could be toxic but was reassured by her neighbour that it was just corn starch

‘I put a picture of Wilbur on Facebook and it turned out a lady who lives a few doors down had a gender reveal party. I guess it’s a boy.’

Sophie, who lives in Heamoor, Penzance, added: ‘I haven’t stopped laughing. I woke up in my sleep laughing. The comments on Facebook made me laugh so much too.’

The pet owner, who also has a five–year–old staffie called Woody, said she washed Wilbur after reading comments that the blue dye could be toxic but she was reassured by Hollie Jenkinson, her neighbour who organised the baby gender reveal, that it was just corn starch.

Sophie added: ‘It’s hilarious. It’s so funny. Everyone at home and at work is cracked up. But all was well in the end. England won the football, my cat was blue and everyone found it funny.’

Wilbur has since been washed off her delightful blue–rinse look and is back to her normal self.

Hollie also thought seeing blue Wilbur was hilarious.

She explained: ‘We thought that it would be a great idea to do a gender reveal for our children in our garden which consisted of the children kicking footballs containing blue corn starch. It all went really well, and my children were really excited.

‘A few hours later I received a message from a family member with a screenshot from a Heamoor community page where a woman, who turned out to be one of my neighbors, was asking why her cat was blue.

‘I immediately burst into laughter when I realised that her cat must have been rolling around in the leftover cornstarch in my garden.

‘I’m so glad that she found the funny side of it and it made the whole situation so much more hilarious. Luckily, after bathing her cat multiple times, the cat is no longer blue.

‘It seemed to have entertained so many people and it has certainly made my gender reveal more memorable.’
