“Just adopted my first cat! But, we noticed these weird little hard things wherever he sleeps. I'm hoping its not worms as he has no other symptoms but was wondering if someone knows what they are.”source ↗

“These are tapeworm segments. Unfortunately this means your car has tapes. But it’s okay! So did mine! Just took them to the vet to get a praziquantel injection and keep them up to date on parasite prevention!”source ↗
