The animal welfare charity is warning cat owners against ‘dangerous’ collars which could leave felines with fatal injuries.

This comes after almost 100 incidents involving cats injured by their own collars have been reported to the RSPCA since the start of the year.

In the last three months there were more than 50 reports and 26 of those were reported to the RSPCA in May alone.

Poor Nugget, the three year old tortoiseshell cat, has been suffering from a large wound in her armpit after getting her leg stuck in her collar - possibly for weeks.

Chunks of fur and skin were pulled off when the collar was finally cut loose.

RSPCA’s Animal Collection Officer Lucy Green was called last month (June 29) by a member of the public in Hutton Cranswick, Yorkshire, who spotted the cat limping around the area.

ACO Green said: “I went out that day and I smelt the poor cat before I saw her. It was pretty putrid and infected. There were a lot of flies on her but luckily there were no fly eggs or maggots in the wound or it could have been a much worse prognosis for her.”

She was treated by vets initially who named her Nugget before she was transferred from the RSPCA Bridlington Branch to the Hull and East Riding Animal Centre where her care is now continuing.

She continued: “It was pretty nasty. Nugget was in a lot of pain. She was lashing out and hissing when I first found her but it must have been because she was in so much pain - as soon as I cut the collar off she was absolutely lovely.

“Staff at the Hull centre said that this is the worst embedded collar injury they have ever seen. As an animal collection officer I would say that it is definitely up there as one of the worst.

“Her wound was so large vets worried it would keep reopening every time she moved if they stitched it up so staff have been working round the clock to keep cleaning and dressing her wound and giving her pain relief and antibiotics. Now it has healed a little bit more they can stitch her up.”

A quick release collar is designed to snap open when tugged with sufficient force and can ensure that a cat is released from its collar if they become stuck.

Elasticated collars, or collars with buckles which do not release without human help can leave cats struggling to free themselves when their legs become stuck - causing horrific injuries.

ACO Green continued: “She is doing really well at the animal home. She is a really friendly little cat but unfortunately we haven't had an owner come forward for her yet.”

One year old black and white cat, named Brian by RSPCA staff, was found in Brierley Hill in the West Midlands on Tuesday (July 11) with his front leg trapped in his collar.

The poor cat was limping around Stourbridge Road with the collar cutting into his armpit.

RSPCA’s Animal Collection Officer Shaun Howden was called to the scene after a member of the public found the cat and tried to cut him free from his collar but Brian became scared and ran away.

ACO Howden said: “I managed to contain him and cut the collar off. He was clearly in a lot of discomfort as the collar had got stuck and ended up around his armpit.

“The collar was embedded into an infected wound and it looked and smelt quite bad.

“There was no ID on the collar and no microchip so we have been unable to locate his owner.”

Brian is now recovering at Birmingham’s Newbrook Farm Animal Centre where his injury is being treated and he is doing much better now.

Alice Potter, RSPCA cat welfare expert said: “These stories serve as an important reminder to cat owners to only use quick release collars on their pets as other collars can be lethal.

“All too often we get called to cats that have become injured due to a collar as there are too many dangerous collars on sale. We would strongly advise against purchasing a collar with buckles that don’t snap open, or collars made from elastic.

“The majority of flea collars are also not advisable as they do not have safety buckles, so we would encourage pet owners to prioritise safety first and give your cat flea treatment another way.

“Cats are natural hunters and curious explorers that enjoy climbing trees or pushing through tight spots and for these reasons it is imperative that any collar is designed to free the cat should they become snagged during their adventures.

“If the collar gets caught on something the cat may try to free itself by using its foot and then, in turn, get its leg stuck with the collar ending up under the cat’s armpit causing painful injury.

“The most reliable way to identify your cat is to have them microchipped rather than having a collar and tag which may fade over time, or hinder them when they explore.

“It is also far better to have to pay for a new collar if your pet has lost theirs than to have to pay for urgent veterinary treatment when your pet becomes injured due to its collar.”
